I recently went to a 50th wedding anniversary in which the groom and bride renewed their vows in a church ceremony. Never once in the very conservative service did either person get credit for the enduring relationship. Rather the minister repeatedly asserted that the success of the marriage was because of the Lord's blessing it. It seemed sad to me to not give these two selfless people a little credit and praise.
Well, I'm not there yet--only about half way--but I don't mind giving God the credit for my enduring (even prospering) marriage. If it was all up to me, I know where it would be.
We insisted on making Him a big part of the wedding ceremony. My wife nixed the traditional wedding march in favor of a contemporary version of "On Christ, the Solid Rock, I stand."
