Don't Waste Your Life: A 5-Day DevotionalSample

Boasting Only in the Cross of Christ, the Blazing Center of the Glory of God

The opposite of wasting your life is to live by a single soul-satisfying passion for the supremacy of God in all things.

How serious is this word “single”? Can life really have that much “singleness” of purpose? Can work and leisure and relationships and eating and lovemaking and ministry all really flow from a single passion? Is there something deep enough and big enough and strong enough to hold all that together? Can sex and cars and work and war and changing diapers and doing taxes really have a God-exalting, soul-satisfying unity?

This question drives us to the death of Jesus on the cross. Living for the glory of God must mean living for the glory of Christ crucified.

Few verses in the Bible are more radical and sweeping and Christ-exalting than Galatians 6:14: “Far be it from me to boast except in the cross of our Lord Jesus Christ, by which the world has been crucified to me, and I to the world.” Or to state it positively: Only boast in the cross of Jesus Christ. This is a single idea. A single goal for life. A single passion. Only boast in the cross. The word “boast” can be translated “exult in” or “rejoice in.” Only exult in the cross of Christ. Only rejoice in the cross of Christ.

Christ is the glory of God. His blood-soaked cross is the blazing center of that glory. By it he bought for us every blessing—temporal and eternal. And we don’t deserve any. He bought them all. Because of Christ’s cross, God’s elect are destined to be sons of God. Because of his cross, the wrath of God is taken away. Because of his cross all guilt is removed, and sins are forgiven, and perfect righteousness is imputed to us, and the love of God is poured out in our hearts by the Holy Spirit, and we are being conformed to the image of Christ.

Therefore every enjoyment in this life and the next that is not idolatry is a tribute to the infinite value of the cross of Christ—the burning center of the glory of God. And thus a cross-centered, cross-exalting, cross-saturated life is a God-glorifying life—the only God-glorifying life. All others are wasted.
