“If you are going to have a marriage that lives in unity, understanding, and love, you must have a little-moment approach to your marriage. God has crafted a life for us that does not careen from huge, consequential moment to huge, consequential moment. You can probably name only two or three life-changing situations you have lived through. Every day we lay little bricks on the foundation of what our life will be. The bricks of words said, actions taken, little decisions, little thoughts, and small-moment desires all work together to form the functional edifice that is your marriage.
So, you have to view yourself as a marital mason. You are daily on the job adding another layer of bricks that will determine the shape of your marriage for days, weeks, and years to come. Things in a marriage go bad progressively. Things become sweet and beautiful progressively. The problem is that we simply don’t pay attention, and because of this we allow ourselves to think, desire, say, and do things that we shouldn’t.”
