The Bible makes lots of distinctions. Why relate it to salvation?
you could say Christ is relating it to salvation by saying let the children come to Him.
coming to Him is being saved; He is Salvation - it's His name
i think Oyster is pointing out that there are such things as children VS. adults, so you see a precedent for the Hebrew idea of barmitvah/batmizvah, and Christ is indicating that children can have faith in Him every bit as much as adults can, when the disciples were thinking children were probably a nuisance to Him and His teaching is only for adults.
