To understand 5:24…you need to understand 5:25. Ponder these words by our Church Father St. John Chrysostom on this very line of scripture:
“Husbands,” saith he, “love your wives, even as Christ also loved the Church.”
Thou hast seen the measure of obedience, hear also the measure of love. Wouldest thou have thy wife obedient unto thee, as the Church is to Christ? Take then thyself the same provident care for her, as Christ takes for the Church. Yea, even if it shall be needful for thee to give thy life for her, yea, and to be cut into pieces ten thousand times, yea, and to endure and undergo any suffering whatever,—refuse it not. Though thou shouldest undergo all this, yet wilt thou not, no, not even then, have done anything like Christ. For thou indeed art doing it for one to whom thou art already knit; but He for one who turned her back on Him and hated Him. In the same way then as He laid at His feet her who turned her back on Him, who hated, and spurned, and disdained Him, not by menaces, nor by violence, nor by terror, nor by anything else of the kind, but by his unwearied affection; so also do thou behave thyself toward thy wife. Yea, though thou see her looking down upon thee, and disdaining, and scorning thee, yet by thy great thoughtfulness for her, by affection, by kindness, thou wilt be able to lay her at thy feet. For there is nothing more powerful to sway than these bonds, and especially for husband and wife. A servant, indeed, one will be able, perhaps, to bind down by fear; nay not even him, for he will soon start away and be gone. But the partner of one’s life, the mother of one’s children, the foundation of one’s every joy, one ought never to chain down by fear and menaces, but with love and good temper. For what sort of union is that, where the wife trembles at her husband? And what sort of pleasure will the husband himself enjoy, if he dwells with his wife as with a slave, and not as with a free-woman? Yea, though thou shouldest suffer anything on her account, do not upbraid her; for neither did Christ do this.

So the wife is to submissive to the mission of the husband, that mission being to love her as Christ loved the Church. You can’t have 5:24 gentlemen unless you’re willing to do 5:25.
