For most Pentecostals there is no other requirement to receive salvation. Baptism with the Holy Spirit and speaking in tongues are not generally required, though Pentecostal converts are usually encouraged to seek these experiences.
 A notable exception is
While the figure of Jesus Christ and his redemptive work are at the center of Pentecostal theology, that redemptive work is believed to provide for a fullness of the Holy Spirit of which believers in Christ may take advantage.
 The majority of Pentecostals believe that at the moment a person is born again, the new believer has the presence (indwelling) of the Holy Spirit.
 While the Spirit dwells in every Christian, Pentecostals believe that all Christians should seek to be filled with him. The Spirit's "filling", "falling upon", "coming upon", or being "poured out upon" believers is called the baptism with the Holy Spirit.
 Pentecostals define it as a definite experience occurring after salvation whereby the Holy Spirit comes upon the believer to
The main purpose of the experience is to grant power for Christian service. Other purposes include power for spiritual warfare (the Christian struggles against spiritual enemies and thus requires spiritual power), power for overflow (the believer's experience of the presence and power of God in his or her life flows out into the lives of others), and power for ability (to follow divine direction, to face persecution, to exercise spiritual gifts for the edification of the church, etc.). 
Pentecostals believe that the baptism with the Holy Spirit is available to all Christians.  Repentance from sin and being born again are fundamental requirements to receive it. There must also be in the believer a deep conviction of needing more of God in his or her life, and a measure of consecration by which the believer yields himself or herself to the will of God. Citing instances in the Book of Acts where believers were Spirit baptized before they were baptized with water, most Pentecostals believe a Christian need not have been baptized in water to receive Spirit baptism. However, Pentecostals do believe that the biblical pattern is "repentance, regeneration, water baptism, and then the baptism with the Holy Ghost". There are Pentecostal believers who have claimed to receive their baptism with the Holy Spirit while being water baptized. 
It is received by having faith in God's promise to fill the believer and in yielding the entire being to Christ.  Certain conditions, if present in a believer's life, could cause delay in receiving Spirit baptism, such as "weak faith, unholy living, imperfect consecration, and egocentric motives".  In the absence of these, Pentecostals teach that seekers should maintain a persistent faith in the knowledge that God will fulfill his promise. For Pentecostals, there is no prescribed manner in which a believer will be filled with the Spirit. It could be expected or unexpected, during public or private prayer. 
Pentecostals expect certain results following baptism with the Holy Spirit. Some of these are immediate while others are enduring or permanent. Most Pentecostal denominations teach that speaking in tongues is an immediate or initial physical evidence that one has received the experience.  Some teach that any of the gifts of the Spirit can be evidence of having received Spirit baptism.  Other immediate evidences include giving God praise, having joy, and desiring to testify about Jesus.  Enduring or permanent results in the believer's life include Christ glorified and revealed in a greater way, a "deeper passion for souls", greater power to witness to nonbelievers, a more effective prayer life, greater love for and insight into the Bible, and the manifestation of the gifts of the Spirit. 
While the baptism with the Holy Spirit is a definite experience in a believer's life, Pentecostals view it as just the beginning of living a Spirit-filled life. Pentecostal teaching stresses the importance of continually being filled with the Spirit. There is only one baptism with the Spirit, but there should be many infillings with the Spirit throughout the believer's life. 
Pentecostalism is a
For Pentecostals, spiritual and physical healing serves as a reminder and testimony to Christ's future return when his people will be completely delivered from all the consequences of the fall.  However, not everyone receives healing when they pray. It is God in his sovereign wisdom who either grants or withholds healing. Common reasons that are given in answer to the question as to why all are not healed include: God teaches through suffering, healing is not always immediate, lack of faith on the part of the person needing healing, and personal sin in one's life (however, this does not mean that all illness is caused by personal sin).  Regarding healing and prayer Purdy states:
On the other hand, it appears from Scripture that when we are sick we should be prayed for, and as we shall see later in this chapter, it appears that God's normal will is to heal. Instead of expecting that it is not God's will to heal us, we should pray with faith, trusting that God cares for us and that the provision He has made in Christ for our healing is sufficient. If He does not heal us, we will continue to trust Him. The victory many times will be procured in faith (see Heb. 10:35–36; 1 John 5:4–5). 
Pentecostals believe that prayer is central in receiving healing. Pentecostals look to scriptures such as James 5:13–16 for direction regarding healing prayer.
 One can pray for one's own healing (verse 13) and for the healing of others (verse 16); no special gift or clerical status is necessary. Verses 14–16 supply the framework for congregational healing prayer. The sick person expresses his or her faith by calling for the
Besides prayer, there are other ways in which Pentecostals believe healing can be received. One way is based on Mark 16:17–18 and involves believers
Many Churches have followed a similar pattern and have given out small pieces of cloth over which prayer has been made, and sometimes they have been anointed with oil. Some most remarkable miracles have been reported from the use of this method. It is understood that the prayer cloth has no virtue in itself, but provides an act of faith by which one's attention is directed to the Lord, who is the Great Physician. 
During the initial decades of the movement, Pentecostals thought it was sinful to take medicine or receive care from doctors.
 Over time, Pentecostals moderated their views concerning medicine and doctor visits; however, a minority of Pentecostal churches continues to rely exclusively on prayer and divine healing. For example, doctors in the United Kingdom reported that a minority of Pentecostal
The last element of the gospel is that Jesus is the "Soon Coming King". For Pentecostals, "every moment is eschatological" since at any time Christ may return.
 This "personal and imminent"
Just as fruit should be evident in the life of every Christian, Pentecostals believe that every Spirit-filled believer is given some capacity for the manifestation of the Spirit.  It is important to note that the exercise of a gift is a manifestation of the Spirit, not of the gifted person, and though the gifts operate through people, they are primarily gifts given to the Church.  They are valuable only when they minister spiritual profit and edification to the body of Christ. Pentecostal writers point out that the lists of spiritual gifts in the New Testament do not seem to be exhaustive. It is generally believed that there are as many gifts as there are useful ministries and functions in the Church.  A spiritual gift is often exercised in partnership with another gift. For example, in a Pentecostal church service, the gift of tongues might be exercised followed by the operation of the gift of interpretation.
According to Pentecostals, all manifestations of the Spirit are to be judged by the church. This is made possible, in part, by the gift of
The gifts of prophecy, tongues, interpretation of tongues, and words of wisdom and knowledge are called the vocal gifts.  Pentecostals look to 1 Corinthians 14 for instructions on the proper use of the spiritual gifts, especially the vocal ones. Pentecostals believe that prophecy is the vocal gift of preference, a view derived from 1 Corinthians 14. Some teach that the gift of tongues is equal to the gift of prophecy when tongues are interpreted.  Prophetic and glossolalic utterances are not to replace the preaching of the Word of God  nor to be considered as equal to or superseding the written Word of God, which is the final authority for determining teaching and doctrine. 
Pentecostals understand the word of wisdom and the word of knowledge to be supernatural revelations of wisdom and knowledge by the Holy Spirit. The word of wisdom is defined as a revelation of the Holy Spirit that applies scriptural wisdom to a specific situation that a Christian community faces.  The word of knowledge is often defined as the ability of one person to know what God is currently doing or intends to do in the life of another person. 
Pentecostals agree with the Protestant principle of
Any Spirit-filled Christian, according to Pentecostal theology, has the potential, as with all the gifts, to prophesy. Sometimes, prophecy can overlap with preaching "where great unpremeditated truth or application is provided by the Spirit, or where special revelation is given beforehand in prayer and is empowered in the delivery". 
While a prophetic utterance at times might foretell future events, this is not the primary purpose of Pentecostal prophecy and is never to be used for personal guidance. For Pentecostals, prophetic utterances are
A Pentecostal believer in a spiritual experience may vocalize fluent, unintelligible utterances (
Within Pentecostalism, there is a belief that speaking in tongues serves two functions. Tongues as the initial evidence of the baptism with the Holy Spirit and in individual prayer serves a different purpose than tongues as a spiritual gift.
 All Spirit-filled believers, according to initial evidence proponents, will speak in tongues when baptized in the Spirit and, thereafter, will be able to express prayer and praise to God in an unknown tongue. This type of tongue speaking forms an important part of many Pentecostals' personal daily devotions. When used in this way, it is referred to as a "prayer language" as the believer is speaking unknown languages not for the purpose of communicating with others but for "communication between the soul and God".
 Its purpose is for the spiritual edification of the individual. Pentecostals believe the private use of tongues in prayer (i.e. "prayer in the Spirit") "promotes a deepening of the prayer life and the spiritual development of the personality". From Romans 8:26–27, Pentecostals believe that the Spirit
Besides acting as a prayer language, tongues also function as the gift of tongues. Not all Spirit-filled believers possess the gift of tongues. Its purpose is for gifted persons to publicly "speak with God in praise, to pray or sing in the Spirit, or to speak forth in the congregation".  There is a division among Pentecostals on the relationship between the gifts of tongues and prophecy.  One school of thought believes that the gift of tongues is always directed from man to God, in which case it is always prayer or praise spoken to God but in the hearing of the entire congregation for encouragement and consolation. Another school of thought believes that the gift of tongues can be prophetic, in which case the believer delivers a "message in tongues"—a prophetic utterance given under the influence of the Holy Spirit—to a congregation.
Whether prophetic or not, however, Pentecostals are agreed that all public utterances in an unknown tongue must be interpreted in the language of the gathered Christians.
 This is accomplished by the
Besides the gift of tongues, Pentecostals may also use glossolalia as a form of praise and worship in corporate settings. Pentecostals in a church service may pray aloud in tongues while others pray simultaneously in the common language of the gathered Christians.
 This use of glossolalia is seen as an acceptable form of prayer and therefore requires no interpretation. Congregations may also corporately sing in tongues, a phenomenon known as
Speaking in tongues is not universal among Pentecostal Christians. In 2006, a ten-country survey by the

In the Oneness view, the Godhead is not three different persons united by one nature, but rather God’s titles. Nevertheless, Oneness Pentecostals hold to the traditional Christian doctrine of the incarnation, professing Jesus Christ to be God. 
In contrast, Trinitarian Pentecostals, and other Trinitarian Christians alike, may accuse Oneness Pentecostals of heresy. The
