1 + 1= 2. Emotional purity + Biblical courtship = Godly marriage. But life doesn’t work that way. You can do everything “right” and your life can still go wrong. You can do everything “wrong” and still be blessed. Rain falls on the good and evil. Time and chance happen to them all. People who follow the courtship formula still get divorced. Or stuck in terrible marriages. Courtship is not the assurance of a good marriage. Life is too complicated for that. Love involves vulnerability. When you choose to love, you are choosing to accept risking a broken heart. No formula can protect you. Life involves risk. Following God involves risk. He is not a “safe” God. But He is good.
I don’t think God likes formulas, because formulas run contrary to faith. Formula says, “I will follow a God that I’ve put neatly in a box, and He will give me the desired results.” Faith says, “I will follow You even when I can’t see where I’m going, even when the world is collapsing around me.” Formula says, “I will not risk. I will be in control of my future.” Faith says “I will risk everything. I will trust Him whom I cannot see, surrender what I cannot control anyway.” Formula is the assurance of things planned for, the conviction of things seen. Faith is the assurance of things hoped for, the conviction of things not seen (Hebrews 11:1). But we are afraid. So we control instead of trust. We don’t take a step unless we can see where we’re going. We build neat little formulas and say “THIS will keep me safe!” Then we blame God when our puny formulas fail.
