Jerry Bridges on Salvation Grace and Living Grace

"My observation of Christendom is that most of us tend to base our personal relationship with God on our performance instead of on His grace. If we've performed well - whatever "well" is in our opinion - then we expect God to bless us. If we haven't done so well, our expectations are reduced accordingly. In this sense we live by works rather than by grace. We are saved by grace but we are living by the "sweat" of our own performance".
