Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: and that repenters and remission of sins should be preached in his name among all nations, beginning at Jerusalem. And ye are witnesses of these things. And, behold, I sent the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye endued with power from on high (Luke 24:46-49).
Then Peter said unto them, repent, and be baptized everyone of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost (Acts 2:38).
But ye shall receive power after that the Holy Ghost has come upon you, and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and utmost part of the earth (Acts 1:8).
Neither Is there salvation in any other: for there is none other name under heaven given among men, where by we must be saved (Acts 4:12).
There is only one God (Deuteronomy 6:4). He is the creator of heaven and earth, and all living beings. He has revealed himself to humanity as the Father (Creator), in the Son (Savior), and the Holy Ghost (indwelling Spirit).
The Bible is the inspired Word of God, giving a true history of the creation of heaven, earth, and humanity and containing a correct prophecy of the ages to come regarding heaven, earth, and the destiny of humanity. Moreover, there is no salvation outside of what is taught in its pages.
Salvation consists of deliverance from all sin and unrighteousness through the blood of Jesus Christ. The New Testament experience of salvation consists of repentance from sin, water baptism in the name of the Lord Jesus Christ for the remission of sins, and the baptism of the Holy Ghost, after which the Christian is to live a godly life (Acts 2:36-41).
We are commanded to live soberly, righteously, and godly in this present
world (Titus 2:12) and warned that without holiness no man shall see the Lord (Hebrews 12:14). We must present our bodies as a living sacrifice holy and acceptable to God which is our reasonable service and be not conformed to this world but be transformed by the renewing of your mind (Romans 12:1).
It is quite impossible to live a holy life without the Holy Ghost. Ye shall receive power, after that the Holy Ghost have come upon you (Acts 1:8).
The Holy Ghost is not a third person in the Godhead, but rather the spirit of God, the spirit of the resurrected Christ. The Holy Ghost is a Comforter that dwells in the hearts and lives of every believer (John 14:16-26).
Water baptism is an essential part of the New Testament church. Water baptism is to be administered only by immersion. Paul stated, we are buried with Him by baptism . . . (Romans 6:4) death, burial, and resurrection are applied to our lives when we experience New Testament salvation. Repent and be baptize every one of you in the name of Jesus Christ for the remission of sins. And ye shall receive the gift of the Holy Ghost. (Acts 2:38).
