Jesus gave up everything. He came to earth and courted the charter members for three and a half years. Behind every sacrifice lies the heart of a servant. In Acts chapter six when the Grecian widows were be neglected concerning their daily needs, there were those who were not acting like Christians. Servants solved the problem.
Marriage vows hold up the high idea of a sacrificing love.
Wives, in the same way be submissive to your husbands so that, if any of them do not believe the word, they may be won over without words by the behavior of their wives, when they see the purity and reverence of your lives. Your beauty should not come from outward adornment, such as braided hair and the wearing of gold jewelry and fine clothes. A beautiful principle is stated here. It is not our words but our attitudes and actions that win others. This is the greatest sacrifice that you will ever give, to live in such a way that your life will win your mate.
