I am going to assume you mean water baptism. Water baptism is something we do to identify with Christ's death burial and resurrection.
The Church should baptize people immediately as was the case in the past, that would end a lot of the anxiety some people have when procrastinating about getting baptized. Example:
Acts 16:30-33
Then he called for a light, and sprang in, and came trembling, and fell down before Paul and Silas,
And brought them out, and said, Sirs, what must I do to be saved?
And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.
And they spake unto him the word of the Lord, and to all that were in his house.
And he took them the same hour of the night, and washed their stripes; and was baptized, he and all his, straightway.
Few things I want to point out: Notice that what they must do to be saved at this time is BELIEVE on the Lord Jesus Christ, and then following that he was baptized.
There are other examples as well. But I do acknowledge that verses like Acts 2:38 are used by some (like the church of Christ) who believe in baptismal renegeration. I understand their argument from that and some other verses, however I believe if we look at the total overall testimony of Scripture, we can conclude that faith saves.
Colossians 2:11-12 links baptism to circumcision in the Abrahamic covenant, and we must remember Abraham was justified through faith prior to being circumcised. It was a sign of the covenant, just like today baptism is something we do to identify with the death, burial and resurrection.
Baptism is a work of righteousness:
Matthew 3:15 Jesus replied, “Let it be so now; it is proper for us to do this to fulfill all righteousness.” Then John consented.
We are not saved by our works of righteousness:
Titus 3:5 he saved us, not because of righteous things we had done, but because of his mercy. He saved us through the washing of rebirth and renewal by the Holy Spirit,
In comparing circumcision of the O.T. to the baptism of the N.T. I quote Matt Slick from
CARM :
" At the same time, we must understand that circumcision did not guarantee salvation to those who received it. It was a rite meant only for the people of God, who were born into the family of God (who were then the Jews). It was an outward sign of the covenant promise. To reject it was to reject the covenant, but accepting it did not guarantee salvation."
I hope this response has been helpful. If you have questions feel free to ask. Also make sure to be a good berean and check from the scriptures if the things told to you by me or anyone else here are so!
