Those who adhere to “faith only” when it comes to salvation often disagree with the necessity of baptism by offering very common objections. Here are three, followed by very quick answers according to the scriptures of God.
Objection 1: Baptism is a work of man that violates Ephesians 2:8 which says, “For by grace you have been saved through faith, and that not of yourselves; it is the gift of God,”
Quick Answer: Whoever said baptism is a work of man? Sure it’s something that a person must submit to, but since when has submission ever earned anyone any thing? Baptism is a work of God and hence, it is not a work of man that earns us anything. “In [Jesus] you were also circumcised with the circumcision made without hands, by putting off the body of the sins of the flesh, by the circumcision of Christ, buried with Him in baptism, in which you also were raised with Him through faith in the working of God, who raised Him from the dead.” (Colossians 2:11-12)
Objection 2: Baptism is to show one is already saved, not to be saved. The “for” in Acts 2:38 is past tense. A person who is wanted “for” robbing a bank is wanted because they robbed a bank in the past, not because they’re going to rob it in the future.
Quick Answer: When a person ignores context they can make a pretext out of almost any scripture! Acts 2:38 says, “Then Peter said to them, “Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit.” Look at the two things the first “and” connects there. A person no more “repents” because they have been saved anymore than they are “baptized” because they have been saved. Repentance always proceeds salvation for the lost as does baptism. “Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead.” (Acts 17:30-31) And by the way, does a person who’s going to the store “for” a loaf of bread go because they already have it, or because they need it? Just asking.
Objection 3: Jesus condemned the lack of faith and not the lack of baptism in Mark 16:15-16 when He said, “…Go into all the world and preach the gospel to every creature. He who believes and is baptized will be saved; but he who does not believe will be condemned.”
Quick Answer: Jesus no more had to condemn the lack of baptism than He did the lack of repentance or confession or faithfulness. Are not these also necessary to be saved? Of course they are! No matter what an unbeliever does they are not saved because they are an unbeliever. Why would anyone want to baptize an unbeliever for the remission of sins when he or she doesn’t even believe in the sins they would be baptized for? Unbelief puts one in a condemned state regardless of anything else. That’s the reason why John 3:18 says, “He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.” In Mark 16:15 baptism still comes before salvation, like it does in the rest of the scriptures for people who lived after the giving of the Gospel of Christ.
Much, much more could be said, but then the answers wouldn’t be so quick would they?
