Then comes a statement which is so profound, for it has not only a literal meaning, but also has a deep spiritual sense. Yes, there will be hostility even in general terms between Satan, and the woman, and woman’s seed, that is to say, all her seed by faith – believers.
This difference is why a believer should never marry an unbeliever. That is why, with the coming of Christ and the Jewish-Gentile church of Jesus Christ, the new arrangements made it a church of regenerate people, because it is no use having children of the serpent and children of the woman in the same church; it does not work. That is a big mistake that some earnest Christian groupings have made in history, to have a mixed multitude just as they had in the Old Testament. It does not work and it is not right, because there will always be hostility between the seed of the woman and the seed of the serpent.
