Mercy in marriage.
We adopt the posture of being willing to experience sin against us as part of building a God-glorifying marriage in a fallen world. Kindness says to our spouse, “I know you are a sinner like me and you will sin against me, just like I sin against you. But I refuse to live defensively with you. I’m going to live leaning in your direction with a merciful posture that your sin and weakness cannot erase.”
