For the sake of argument let's say Paul was saved on the road to Damascus. There was no one there who could Baptize him, DUH, :BangHead: but he was ordered into Damascus by the Lord where his eyesight was healed and he was Baptized. Reading the account there is no reason to believe it all was not done right away as soon as he was in the company of another Christian to baptize him. Read Acts 22
Also John's Baptism was a Baptism of repentance not in the name of the Lord washing away sin, big difference.
Paul being ordered to town and to wait shows that
there can be and for good reason a delay between conversion and baptism. This delay has NOTHING to do with a judgment of whether one is "really saved" or not. Because there was a delay (as you admit) no matter the "why", your statement that "Baptism is to be done right after salvation as is every example in Scriptures" has by this example been shown false.
I once knew a man who was very consumed with evil. He was gloriously converted, and desired to be baptized, however he delayed the baptism for time to gather all the old crowd that would come. It took a few weeks, but the results were awesome. Watching the large group of heathens enter the church was almost humorous. I don't know who was more nervous the assembly, or the large group of heathen. Both were uncomfortable, and many most wonderful testimonies of later conversion resulted from that man's decision to invite his former friends.
By your posts, you would hold that such was placing the man in a state of sin.
But it is God who looks upon the heart and motivations.
