Which are “His” and which are “His Father’s”?
That’s a subject pregnant for a lot of dispute (no pun intended). Disagreements in Christendom are stark over this, but at least some aver that many Jewish people have not yet reached the understanding of the Christ needed to make a genuine acceptance (or rejection) but that when they do, they will accept. Those people though living today would be in the position of the Old Testament saints. Others hold a more pessimistic view. Whatever the case, Christians preach the gospel to all men without discrimination.
