Do not say, “I’ll pay you back for this wrong!” Wait for the LORD, and he will avenge you. ~ Proverbs 20:22 (NIV)
Oh how we crave a strong and punishing retaliation against that person who crossed us.
Revenge is God's job. And when we attempt to do God's job - we fall short, we destroy others, and we lose our credibility as Christians, and as neighbors. Taking revenge into our own hands is like telling God that we can do His job better than He can.
There is a way to conquer it... it's the short pause between the offense and your response.
The win comes when we learn to recognize revenge as it rushes into our heart. Look for that pause that happens between the offense and the thought of retaliation. Pray for God to fill that moment with His spirit, and ask God to take over.
