See?
This is precisely the type of "hair splitting" that I referred to earlier (but not specifically in relation to you).
I mean, Cornelius was water baptized right after he believed, so why don't we all just see the two (believing and being baptized) as two things which ought to occur on the same day or at the same time? Obviously (although not to some), the believing part has to come first, but water baptism ought to immediately follow, even as it did all throughout the book of Acts.
What does it mean to "believe" anyway?
Well, we're all familiar with the following:
Romans chapter 10
[6] But the righteousness which is of faith speaketh on this wise, Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down from above):
[7] Or, Who shall descend into the deep? (that is, to bring up Christ again from the dead.)
[8] 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;
[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.
[12] For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
[13] For whosoever shall call upon the name of the Lord shall be saved.
This "righteousness which is of faith" was actually in existence way back in Old Testament times and Paul actually cited from Deuteronomy as his "proof text" for what he was about to say in relation to the same. Yes, Paul cited the following:
Deuteronomy chapter 30
[11] For this commandment which I command thee this day, it is not hidden from thee, neither is it far off.
[12] It is not in heaven, that thou shouldest say, Who shall go up for us to heaven, and bring it unto us, that we may hear it, and do it?
[13] Neither is it beyond the sea, that thou shouldest say, Who shall go over the sea for us, and bring it unto us, that we may hear it, and do it?
[14] But the word is very nigh unto thee, in thy mouth, and in thy heart, that thou mayest do it.
Yes, this is exactly what Paul cited in Romans 10:6-8 and it has to do with a BELIEF that Jesus has "descended into the deep" AND "ascended up to heaven". If anyone BELIEVES the same, then why wouldn't they be water baptized in that water baptism signifies being buried with Christ (or descending into the deep with Him) and also being raised up and seated in heavenly places in Christ Jesus when one comes out of the water (or ascending up to heaven with Him)?
Seriously, this "hair splitting", and I'm not specifically referring to you, but to others instead, simply needs to stop. If you BELIEVE that Christ died, was buried, arose from the dead and ascended back to heaven, then water baptism ought to follow immediately in that it is "the answer of a good conscience towards God by the resurrection of Jesus Christ: Who is gone into heaven, and is on the right hand of God; angels and authorities and powers being made subject unto him" (I Peter 3:21-22).
