Pray that your husband will safeguard his heart against inappropriate relationships with the opposite sex. Pray that his heart will be pure and undivided in his commitment to you. (Prov. 6:23-24, 26; Rom. 13:14)
"For he commandment is a lamp and the teaching is light;And reproofs for discipline are the way of life, To keep you from the evil woman,From the smooth tongue of the adulteress."
Proverbs 6:26 (New American Standard Bible)
"For on account of a harlot one is reduced to a loaf of bread,And an adulteress hunts for the precious life."
Romans 13:14 (New American Standard Bible)
"But put on the Lord Jesus Christ, and make no provision for the flesh in regard to its lusts."
