There is also an antitype which now saves us—baptism (not the removal of the filth of the flesh, but the answer of a good conscience toward God), through the resurrection of Jesus Christ, who has gone into heaven and is at the right hand of God, angels and authorities and powers having been made subject to Him.
1 Peter 3:21,22
Talk about taking a passage out of context!
Baptismal candidates must acknowledge publicly that on the basis of Jesus' sacrifice they have repented of their sins and have dedicated themselves to Jehovah
Here's your public acknowledgement... it's not baptism by water that saves, but a spiritual baptism (death to the flesh and being born of the spirit), a spiritual rebirth.
But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; 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.
"But those things that proceed out of the mouth come from the heart..." (Matt 15:18)
If you believe in your heart on Jesus Christ, then you will not be ashamed and from your mouth public proclamation will be made. As followers of Christ, one will be baptised by water because Jesus commanded us that we should and if we love His commands, that's what we'll do. But to say one must be baptised by water in order to be saved is to add works to a salvation which comes only by the grace of God through faith.
For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.
The thief on the cross was not baptized by water and the Lord said, "today you will be with Me in paradise." (Luke 23:43) Why did Jesus say it? Because the thief believed on Jesus Christ and was saved. God revealed that truth to him so it remains that God was gracious to save a thief, even gracious enough to save me. Savation is by grace, by faith, not by works or by a water baptism. Even John said that though he baptized by water, one was coming who would baptize us with the Holy Spirit and with fire. (Matt 3:11)
And being assembled together with them, He commanded them not to depart from Jerusalem, but to wait for the Promise of the Father, “which,” He said, “you have heard from Me; for John truly baptized with water, but you shall be baptized with the Holy Spirit not many days from now.”
