nope. John baptized for the coming kingdom,
Ephesians 2:8-10
King James Version
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9 Not of works, lest any man should boast.
10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
Baptism is a work.
Romans 10:9-12
King James Version
9 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.
10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
11 For the scripture saith, Whosoever believeth on him shall not be ashamed.
This is the formula for salvation and no Baptism is mentioned.
JOhn 3:
18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
36 He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.
No Baptism.
John 1:33
And I knew him
not: but he that
sent me to baptize with water, the same said unto
me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which
baptizeth with the Holy Ghost.
This is the baptism that saves- the Holy Spirit. that comes the moment we believe.
The pentitent thief was not baptized.
1 Cor. 1:
13 Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?
14 I thank God that I baptized none of you, but Crispus and Gaius;
15 Lest any should say that I had baptized in mine own name.
16 And I baptized also the household of Stephanas: besides, I know not whether I baptized any other.
17 For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect.
18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
If water baptism is essential for salvation, why did Paul say he was not sent to baptize?
So I take it you totally reject deathbed conversions as they cannot be baptized.
