Obliged to Christian Living

We skipped to this Lord's Day in order to consider further the sacraments and that we are justified by Grace alone. We have been saved by Christ and nothing of our own doing. Why then must we live a Christian life if we have been saved? Paul corrects this attitude and brings us back to needing to live a sanctified life. We have been justified, not by any of our works. As a result, the law of God leads us in a proper walk as we are obliged to live a Christian life out of thankfulness for our salvation.
