Does 2 Samuel 12:23 support the salvation of babies who die when a week old? The argument put forth is since David said he would go to him. The assumption here is David was referring to Abraham's bosom, and not simply joining him in the grave. But Jacob said something similar, I will go down to Sheol in mourning for my Son. And scripture says if you do not believe in Him you are condemned already in unbelief. All babies are condemned already.
If we consider the actual foundation, it is conjecture without biblical support (1) Election of individual foreseen babies, (2) they are given faith irresistibly without hearing the gospel and (3)God is love and would not condemn the babies of the elect.
Fifty days after the resurrection of Jesus Christ the firstborn of the dead, Peter told at least three thousand plus people that the prophet and king David was at that time both dead and buried and his sepulchre is with us unto this day. After establishing exactly where David is he makes the point that being David is still dead and buried that is his soul is in hell (Hades) he,
David was prophesying of Jesus Christ that his soul was not left in hell (Hades) neither his flesh did see corruption why because the soul of Jesus had been raised from hell (Hades) and neither did his body see corruption.
Where do you think the infant son of David was on that day?
