When the Son of God was made flesh and became both God and man in two natures and one person, he committed himself to his people forever, for having taken our nature he has redeemed it from destruction and raised it to the highest glory; he will never put it off again. Mankind has not been created in vain, but Christ has preserved the race through his elect people.
Some who claim to be evangelicals make this verse the basis of association with liberals and other nominal believers, but Scripture nowhere gives encouragement to false ecumenical unity. The only unity approved by Scripture is unity in the truth, practised by those who obey and love Christ and accept all that he taught as binding on them. Those who are determined to justify their disobedience to Scripture on the basis of this verse, and to associate with any who can manage to utter some emaciated confession of faith, are fooling only themselves.
