" As the psalmist prayed so many centuries ago, “If you, O Lord, should mark iniquities, O Lord, who could stand?” (Ps. 130:3). The answer is obvious: no one. The bad news is that the Lord does mark iniquities. The blessed person is the one to whom the Lord does not impute guilt. This is the core of the gospel. "
