Marriage is the intimate union and equal partnership of a man and a woman. It comes to us from the hand of God, who created male and female in his image, so that they might become one body and might be fertile and multiply (See Genesis chapters 1 and 2). Though man and woman are equal as God’s children, they are created with important differences that allow them to give themselves and to receive the other as a gift.
In Malachi, God tells the Israelites that He will not accept their offerings because they have been unfaithful to the wives of their youth. This shows how much God cares about marriage being kept intact. Not only that, but He tells them He was seeking “godly offspring.” This is a puzzling passage, and has been interpreted to mean a) that godly offspring are the purpose of marriage;
Our attempts to follow God’s commands in our own strength tend to end in failure, and that failure tends to make the believer more aware of his dependence on God and more open to the Spirit’s work in him, which tends to result in godliness. And godliness helps us to follow God’s commands. So, marriage is very helpful for the one trying to live a godly life; it helps to scrub the heart clean of selfishness and other impurities.
Marriage also protects individuals from sexual immorality (1 Corinthians 7:2). The world we live in is full of sexual images, innuendo, and temptation. Even if a person doesn’t pursue sexual sin, it pursues him or her, and it is very hard to escape it.
