The Apostle Paul is quoting Deuteronomy 32:35 urging others not to seek justice themselves out of anger or spite. For Proverbs 20:22 tells us, “Do not say, ‘I’ll pay you back for this wrong!’ Wait for the Lord, and He will deliver you.” But when we’re angry and frustrated, and think no one has our back…we tend to react badly. It’s at that point that we need to take a deep breath and remember that the Lord tells us that He will defend us. (Jeremiah 51:36)
