You said, “baptism is a work of man”. John’s baptism was different than the one Christ commanded (See Acts 19:1-3), but there is a point that was made by Jesus; “The baptism of John—where was it from? From heaven or from men?” (Matt. 21:25)
I ask, "The baptism of Christ - where was it from? From heaven or from men?"
Who commanded baptism? If God commanded it, then it is not simply “a work of men”. No ordinary man invented it! It is a work that was established, authorized and commanded by God! It is from God and not from men!
Baptism is the point in time when a repentant believer becomes a Christian (saved). Baptism is how God has appointed for us to receive the gift of salvation.
1 Peter 3:21 says, “…baptism now saves you -- not the removal of dirt from the flesh, but an appeal to God for a good conscience – through the resurrection of Jesus Christ.” (NASB)
Jesus said, “He that believes and is baptized shall be saved.” (Mark 16:16)
Many will tell you someone believes, is saved, and then he shall be baptized. This is not the same thing Jesus said. It is not in the same order.
What would Jesus have said if he had meant, “He that believes and is baptized shall be saved”?
I believe he said what he meant. I believe Jesus! “He that believes not shall be condemned.” (Mark 16:16)
Many agree that baptism is commanded by Christ, but they say it is not necessary for salvation. However, Heb. 5:9 says, “He became the author of eternal salvation unto all them that obey him.”
According to this verse, in order to be saved it is necessary to obey Christ, therefore it is necessary to be baptized since Christ commanded it.
Acts 2:38 says that baptism is “for the remission of sins”, “unto the remission of sins” or “so that your sins will be forgiven”. (Depending on which translation you read.)
In the conversion of Saul (Paul), Acts 22:16 says he was commanded to be baptized and wash away his sins. Can we be saved if our sins remain? The blood of Christ washes away sins (Rev 1:5) .
Romans 6:3-4 says we are “baptized into Christ”. Can we be saved outside of Christ? (See Gal. 3:27 also.) These verses in Romans also say we are “baptized into his death”. At Christ’s death is where his saving blood was shed and offered for our sins. We must contact His death to contact that blood! Can we be saved if we have not contacted His death?
How can our sins be washed away by the blood (Revelation 1:5) if we have not contacted that blood? To contact the blood, we must contact His death where the blood was shed!
Romans 6 also says at baptism we “rise to walk in newness of life.” At a birth there is a new life. Can we be saved if we have not been “born again” to this new life in Christ?
After Jesus gave the command about baptism, every conversion example specifically mentions baptism and it was always immediately done.
Some point to the thief on the cross, before Jesus commanded of baptism. He could not have obeyed a command that had not yet been issued. Also the death, burial, and resurrection that baptism now represents had not occurred at that time. How could he be baptized into Christ's death, when Christ had not yet died? How could he have been “buried with Christ” (Col. 2:12) when Christ had not yet been buried? How could he rise from baptism “in the likeness of His resurrection” when Christ had not yet risen?
Those before Christ's death lived under the Old Testament. The New Testament came into effect after Christ died and rose again. (Hebrews 9:15-17) And remember, it was after His death that Jesus commanded baptism (Mark 16:16, Matt. 28:18-20) All those who now live after that point in time are subject to the New Testament and to that command.
The thief on the cross was at the scene of Christ's death. We are not in that position. Again, it is through baptism that we contact His death!
Paul is a good example of baptism’s necessity. He spoke to Jesus, called Him “Lord” and he asked what he needed to do to be saved. Jesus told him to go into the city and it would be told to him what he “must do”. In the city he fasted for 3 days and he prayed. (Acts 9:9-11) Many say he was saved at that point, but he still had not been told what he “must do”.
Then he was told to be baptized and wash away his sins “calling on the name of the Lord”. Obviously, “calling on the name of the Lord” involved more that saying ‘Lord’, more than praying, more than belief and more than repentance. Saul had done all of these, but he still needed to call on the name of the Lord!
The phrase “calling on the name of the Lord” means to rely on His authority. Saul had not done this until he did what the Lord instructed, namely “be baptized”. (Mark 16:16, Matt. 28:18-20, read Luke 24:47 along with Acts 2:5 & 38).
Note, even though he had not eaten or drank for 3 days, he was baptized before he took food. (Acts 9:18-19) This shows the urgency of baptism. In fact, none of the new converts in the book of Acts ate, drank, or slept until they were baptized!
