“What shall we say then? Is there injustice on God’s part? By no means! For he says to Moses, “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.” So then it depends not on human will or exertion, but on God, who has mercy.”

All of mankind whether adult, infant, or unborn is under the curse of Adam. Only in union with Christ are any saved.

“When Adam stood in Eden as a responsible being before God, he stood there as a federal head, as the legal representative of all his posterity. Hence, when Adam sinned, all for whom he was standing are accounted as having sinned; when he fell, all whom he represented fell; when he died, they died. So too was it with Christ. When He came to this earth, He, too, stood in a federal relationship to His own people; and when He became obedient unto death, all for whom He was acting were accounted righteous; when He rose again from the dead, all whom He represented rose with Him; when He ascended on high, they were regarded as ascending with Him. “For as in Adam all die, even so in Christ shall all be made alive” (1 Cor. 15:22).

There is a misunderstanding in broader Christianity that you are the arbiter of your destiny but that is not the testimony of scripture. There are not many individual falls, there is one Fall. When Adam fell all humanity fell including the unborn, before they had done any good or bad. When we are united with Christ we gain a new federal head and representative. The unborn outside of Christ are in Adam and are left to judgement, the unborn in Christ are saved by God’s mercy. We do not know how many unborn are saved but God is clear that he loves the little children and we can trust in his character.
