And the one who attends to your answer is like a fellow holding a sieve to catch the milk. At course, at one level, the question of whether babies go to heaven or hell when they die makes perfectly good sense. Babies do die, whether in the womb or out, and we may reasonably ask about their fate. In fact, the pastor is hit smack in the face with this question if he serves any time at all. But at another level, it's a very odd question.
Logicians call it a complex question.
It smuggles in an unestablished presupposition. In this case, it implies that babies are appropriately residents of either heaven or hell. Isn't it odd to think of a preemie, upon his death, falling into the torments of hell to be tortured throughout eternity. There he writhes, uncomprehending and uncomforted. On the other hand, isn't it odd to think of an equally uncomprehending baby, basking eternally in the splendors of heaven, unable to understand the Cross and the fellowship of the saints.
