He answered, “Have you not read that he who created them from the beginning made them male and female, and said, ‘Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh’? So they are no longer two but one flesh. What therefore God has joined together, let not man separate.”
A friend of mine gave me some great advice years ago. He said, “you need to think of your marriage as a series of circles. First comes you and your spouse, in the center of that circle is God. You protect this circle from all outside influences. Second comes you children, then your friends, then acquaintances and so on.” Too many people allow outside influences to enter this inner circle, keep it between you and God.
