Excerpt from the book:
The greater we see the debt of our sin forgiven, the greater will be our debt of gratitude and love to Him who lavished such grace on us. That gratitude increases as we grow in comprehension of the cost for such forgiveness. In fact, that growing realization of the wonder of God’s forgiveness characterizes Christian maturity. When the Spirit initially opens our eyes to our sin and to God’s remedy in Christ, we have a degree of appreciation. As we grow in our relationship with God, we discover that God is holier than we had conceived. In his vision, Isaiah the prophet was never more acutely aware of his sin than when he beheld the holiness of God. In the light of God’s glory, we find our sin more heinous and extensive than we ever realized, meaning that the debt of that sin was more massive than we had ever grasped.
As of this writing, the federal debt of the United States is a little more than 19 trillion dollars. That’s 19 with twelve zeros. We can hear that and understand that is a lot of money, but we can’t really comprehend it. But the more we try to, the more incredulous we will grow. How much more when it comes to grasping the magnitude of the debt of our sin in light of the holiness of God!
But here is where our knees buckle in wonder and our hearts flood with love, gratitude, and awe. Where an audit of the debt of our sin exposes greater and greater liability to the justice of God’s holiness, every invoice we find will be stamped “paid in full” at Calvary, where Jesus announced, “It is finished.” This was a pronouncement that the debt of the sin He bore was paid—in fullness and finality.
As we continue to mature in the faith and see that chasm between a holy God and a sinful us widening, and the cross of Christ sufficient still, our love for God deepens and our gratitude for His mercies grows. This is the glory of the gospel, the potency of its saving power. The greater our sin, the more glorious God’s grace. The apostle Paul expresses it this way: “But where sin abounded, grace abounded much more, so that as sin reigned in death, even so grace might reign through righteousness to eternal life through Jesus Christ our Lord” (Rom. 5:20–21). What an astounding bookkeeping measure! No matter how high the mountain of our debt of sin, it is dwarfed by the grace of God in Christ. Everest is eclipsed. What that means is that no matter where sin is found in our lives, at any point, to any degree, it has been accounted for by God and paid for by Christ.
