'People tend to make two mistakes when they think about the redeemed life. The first is to understimate the sin that remains in us; it's still there and it can still hurt us. The second is underestimate the strength of God's grace; God is determined to make us new.
As a result, all Christians need to say two things. We admit that we are redeemed sinners. But we also say boldly and joyously that we are redeemed sinners.'
Cornelius Plantinga Jr., Beyond Dioubt: Faith-Building Devotions on Questions Christians Ask, p.89.
