our repentance and confession marries God’s forgiveness to produce something for God’s building

In a way, if in our Christian life we didn’t have a great failure – something that we do which makes the other saints shake their head when they think about it – we cannot say we have experienced a great repentance matched by God’s forgiveness… No, we don’t want to say, Let us do evil so that good may later come. We don’t want to tempt God nor do we desire to willingly fail, but we may fail and commit a great sin – we may have a great failure – and there will be a deep repentance that will follow.
