Therefore, God’s Word says, a man shall “leave” his parents and “cleave” to his wife and they shall become one flesh (Gen. 2:24). I’d like to emphasize that the words, “leave,” and “cleave,” are words used in the context of the covenant with the LORD. When Israel leaves the LORD, she is unfaithful to her covenant with Yahweh. When she clings to the LORD, she is faithful to her covenant (Deut. 28:20; Hos. 4:10). Marriage, then, as God has willed it, is a covenant relationship between a man and a woman.
Now this covenant relationship is to be indissoluble. It is to be permanent and binding. It is to be indissoluble, unbreakable, and indestructible. God shall make it so. Jesus confirms the unbreakability of marriage by saying, “Therefore, what God has joined together, let no man put asunder.”
Therefore, marriage is not about keeping in love. It is keeping the covenant. Your duty, Dandin, and your duty April, is to keep the covenant. That is what God commands you to do.
Now when you “leave” your parents and “cling” to your wife or husband, it means that all other loyalties are superseded. All other loyalties take second priority. Your marriage takes priority over other loyalties—whether it is loyalty to your parents, your family, or your friends.
Dandin, your priority is your wife, not your mother or father. April, your priority is your husband, not your friends and family. That is how you keep the covenant.
Today, selfishness and adultery are destroying marriages. Flee from all appearance of evil. Marriage means that you will no longer look at other women. You will only look at one woman. That is how you keep the covenant.
 Matthews, Genesis, 222.
