The human heart longs for justice, to see evil punished: we say, “Don’t get mad; get even!” We demand that wrongs against us and our loved ones be righted, that sin be paid for, that the crooked be made straight. Our sense of injustice, that evil goes unpunished in this life, can be maddening, driving us to bitterness.
Our instinctive longing for justice is beautiful; it’s God’s image at work in us, even proving His existence, but there’s a problem: we’re unjust. We seldom see our own sins rightly, and our response to evil is usually warped; we exact more than we should.
So God says, “Vengeance is mine, I will repay.” (Ro 12:19) He wants perfect justice more than all the rest of us combined, but only He knows what it looks like.
God is perfectly just, and only God is perfectly just; He will make all the crooked places straight (Is 40:4); He will right all wrongs … even our own. It’s an awesome mystery how God’s justice and mercy work together (Ps 89:14), how He can offer eternal salvation to sinners, His own Son taking our place and satisfying His own indignation against us. We do well to receive His mercy rather than the second death, and to rejoice when others do … especially our enemies. (Mi 6:8)
How and when God makes everything right is up to Him; when He does it will be supremely satisfying, beautiful beyond thought! (Re 15:3-4) Enjoying it now in hope, before He does, glorifies Him and gives us peace.
