This passage shows us the high standard of sexual purity for the believer, and the sad example of Esau, who exemplifies sexual immorality and ungodliness. In order to honor marriage and live lives of purity, we should not delay marriage unnecessarily, not demand that it be more than God intended it to be, not demean the alternative calling of singleness, and not despise the sexually broken, but rather hold out the grace of Jesus which we all need.
