As I write this, my wife and I mark our 49th anniversary. We’re recalling the three points of our premarital counseling: move 1,000 miles from either set of parents for at least the first year, pray and read your Bible together daily, and get help before doing anything drastic like separating.
Our counselor (and wedding officiant) was Dr. Tim LaHaye, who now is home with the Lord. He was a great pastor, and we did indeed go on to see his wisdom through the years. Of course, for a new couple, the actual miles between them and their parents is not really the issue. What is important is the “leave and cleave” principal. Also, we have seen that Bible reading and prayer have carried us through every life situation. The couple who prays and reads the Word together understands they are not just a twosome; with Jesus Christ they are like that cord of three strands which is not easily broken.
In any marriage stresses, go to your greatest resource: the life-giving, self-sacrificing love of Jesus. It can see you beyond 49 years!
