The Westminster Shorter Catechism says that Christ executes the office of king by “subduing us to himself, in ruling and defending us, and in restraining and conquering all his and our enemies” (Q&A 26). All who oppose this work do so in vain. He will conquer the hearts of His elect, drawing them all to Himself. He will defeat His enemies and ours. He is the mighty King and Lord of all, and we need not fear anything if we are in Him.
