Love is patient and kind; love does not envy or boast; it is not arrogant or rude.

– Jesus' parable of the wise builder illustrates the importance of not just hearing God's Word, but actively putting it into practice. A marriage built on obedience to Christ's teachings will be resilient against life's storms. Consider the 'house' of your marriage: is it built on the solid rock of obedience, or the shifting sands of mere sentiment?

The path of steadfastness in marriage is paved with intentional acts of love, forgiveness, and mutual support, all grounded in the unchanging truth of God’s Word. By embracing these principles, couples can build a resilient union that withstands the inevitable storms of life.
