A favorite section from R.C. Sproul’s classic, The Holiness of God:
When our holy war with God ceases; when we, like Luther, walk through the doors of paradise, when we are justified by faith, the war ends forever. With the cleansing from sin and the declaration of divine forgiveness we enter into an eternal peace treaty with God. The firstfruit of our justification is peace with God. This peace is a holy peace, a peace unblemished and transcendent. It is a peace that cannot by destroyed.
When God signs a peace treaty, it is signed for perpetuity. The war is over, forever and ever. Of course we still sin; we still rebel; we still commit acts of hostility toward God. But God is not a cobelligerent. He will not be drawn into warfare with us. We have an advocate with the Father. We have a mediator who keeps the peace. He rules over the peace because He is both the Prince of Peace and He is our peace.
We are now called the children of God, a title granted in blessing to those who are peacemakers. Our sins are now dealt with by a Father, not a military commander. We have peace. It is our possession, sealed and guaranteed for us by Christ. (chapter 7)
A call to and reason for worship for all who have experienced this peace!
