"He who is alone with his sin is utterly alone. It may be that Christians, notwithstanding corporate worship, common prayer, and all their…service, may still be left to their loneliness. The final break through to fellowship does not occur, because though they have fellowship with one another as believers and as devout people, they do not have fellowship as the undevout, as sinners. The pious fellowship permits no one to be a sinner. So everybody must conceal his sin from himself and the fellowship. We dare not be sinners. Many Christians are unthinkably horrified when a real sinner is suddenly discovered among them. So we remain alone with our sin, living lies and hypocrisy. The fact is we are sinners. But it is the grace of the Gospel, which is so hard for the pious to understand, that it confronts us with the truth and says: You are a sinner, a great desperate sinner; now come as the sinner that you are, to God who loves you…He does not want anything from you, a sacrifice, a work; He wants you alone. God has come to save the sinner."
