Even though we do the same thing around the same time in our service every Sunday morning, those who benefit most from our time of confession are probably those who are most surprised. I’m not talking about visitors. In one sense those of us who participate regularly should be more surprised each successive week that we have more sin to confess.
We are Calvinists so we have a hold on the petal of total depravity, even the one-pointers. We believe that all have sinned and fall short of the glory of God. We believe that even when God regenerates us He doesn’t sanctify away all our sinful practice instantly but progressively. We believe that a Christian who says that he has no sin makes God a liar. So how can I say that there is a place for surprise when we come to see our sin?
We are surprised because we also believe the gospel. We believe that God saves sinners and that means we are dead to sin–in reality. Believing the gospel means that we’ve been raised with Christ to walk in newness of life–right now. Believing means that God has granted to us all things pertaining to life and godliness–for the present. Believing means that God set the seal of His Spirit on us to make us more holy–before heaven.
We are likely to be surprised by an exhortation that exposes another sin to confess because we believe that the gospel has taken root in our lives. Our optimism, our hope in the gospel, motivates better confession.
G. K. Chesterton observed that only optimists reform anything. Cynics and pessimists see evil and, well, they knew it would be. Optimists are still startled by injustice. “What?! That’s not right! That doesn’t belong!” Anyone can rail against unrighteousness. Only a man with gospel hope will want better.
The pessimist resents evil solely because it is a grievance. The optimist resents it also, because it is an anomaly; a contradiction to his conception of the course of things.All Things Considered, 53
We are not naive about sin, and certainly not sentimental towards it. We acknowledge that we are sinners being saved but we also acknowledge that the power of gospel overcomes the power of our sin. God calls us to mortify our sins, put them to death. He also calls us to believe that sin will in fact be put to death and stay dead, even as we confess it and repent.
