I've heard 2 Samuel 12:23 used.

Quote
18 Then it happened on the seventh day that the child died. And the servants of David were afraid to tell him that the child was dead, for they said, "Behold, while the child was still alive, we spoke to him and he did not listen to our voice. How then can we tell him that the child is dead, since he might do himself harm!"
19 But when David saw that his servants were whispering together, David perceived that the child was dead; so David said to his servants, "Is the child dead?" And they said, "He is dead."
20 So David arose from the ground, washed, anointed himself, and changed his clothes; and he came into the house of the LORD and worshiped. Then he came to his own house, and when he requested, they set food before him and he ate.
21 Then his servants said to him, "What is this thing that you have done? While the child was alive, you fasted and wept; but when the child died, you arose and ate food."
22 He said, "While the child was still alive, I fasted and wept; for I said, 'Who knows, the LORD may be gracious to me, that the child may live.'
23 "But now he has died; why should I fast? Can I bring him back again? I will go to him, but he will not return to me."

What I'd like to know is how they can jump to these conclsions, and yet still believe in original sin and total depravity.

By the way, if David is not saying he will see his son in heaven (even if he was saying that, it wouldn't be enough to make a generalization), then what exactly is he saying? I have some ideas: that David is speaking in generalities about the fact that his son cannot be brought back from death, and that one day David will die too.

True godliness is a sincere feeling which loves God as Father as much as it fears and reverences Him as Lord, embraces His righteousness, and dreads offending Him worse than death~ Calvin
