The Essence of Sin and Salvation - John Stott

For the essence of sin is man substituting himself for God [Gen. 3:1-7], while the essence of salvation is God substituting himself for man [2 Cor. 5:21]. Man asserts himself against God and puts himself where only God deserves to be; God sacrifices himself for man and puts himself where only man deserves to be.
