No relationship is more fundamental than the relationship between a husband and a wife. It's the primary relationship. Father/mother/child relationship is secondary. And therefore your spouse and your marriage has to be your #1 priority; it has to come before your career; it has to come before your friends; it has to come before your children--that's a very hard one especially nowadays, it really is; it has to come before anything else.
Now afterwards I got a number of questions about this. Somebody came up to me and said to me, "All right, what if the man thinks that he is putting his marriage first but the woman thinks he's not? How do you solve that?" Or, "What if the woman thinks she is putting her marriage first and the man thinks she isn't? How do you solve that?"
It's simple: if one person thinks the marriage is first and the other person thinks it's not, then it's not. It's simple.Dr. Timothy Keller, Marriage as Priority & Friendship September 8, 1991
