One must understand that CONFESSION of faith in Jesus as the Christ, the savior of the world, the Son of God, is essential to become a child of God. There is no salvation in any other name.
“Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved” (Acts 4:12). Jesus plainly said, “Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven. But whosoever shall deny me before men, him will I also deny before my Father which is in heaven” (Matthew 10:32-33). “For it is written, As I live, saith the Lord, every knee shall bow to me, and every tongue shall confess to God” (Romans 14:11). The apostle Paul reminded the brethren in Rome “that if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. For the scripture saith, Whosoever believeth on him shall not be ashamed” (Romans 10:9-11). The man from Ethiopia understood the teaching of Philip about forgiveness of sins and desired to be baptized to receive forgiveness. “And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God“ (Acts 8:37). He immediately was then baptized. “Whosoever shall confess that Jesus is the Son of God, God dwelleth in him, and he in God” (1 John 4:15). “For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist” (2 John 1:7). “Nevertheless among the chief rulers also many believed on him; but because of the Pharisees they did not confess him, lest they should be put out of the synagogue: For they loved the praise of men more than the praise of God” (John 12:42-43). Though confession of faith in Christ is essential, it is not all that is required. Unless it is preceded by faith and repentance and followed by water Baptism, it is simply “words in the air.” Do you believe? Will you publicly confess Christ?
