I can totally see your point... but I tend to lean towards something a little different based on other scriptural evidence... which would take a couple paragraphs to explain if you would like me to...
Main point being.. he was to be in Heaven even though no baptism could possibly take place.
Here's the verse that I made reference to in various versions.
John 20:17
(ASV) Jesus saith to her, Touch me not; for I am
not yet ascended unto the Father: but go unto my brethren, and say to them, I ascend unto my Father and your Father, and my God and your God.
(BBE) Jesus said to her, Do not put your hand on me, for I
have not gone up to the Father: but go to my brothers and say to them, I go up to my Father and your Father, to my God and your God.
(ESV) Jesus said to her, "Do not cling to me, for I
have not yet ascended to the Father; but go to my brothers and say to them, 'I am ascending to my Father and your Father, to my God and your God.'"
(KJVR) Jesus saith unto her, Touch me not; for I am
not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God.
(MKJV) Jesus said to her, Do not touch Me, for I
have not yet ascended to My Father. But go to My brothers and say to them, I ascend to My Father and Your Father, and to My God and your God.
