We start each day with our personal security resting not on the accepting love of God and the sacrifice of Christ but on our present feelings or recent achievements in the Christian life. Since these arguments will not quiet the human conscience, we are inevitably moved either to discouragement and apathy or to a self-righteousness which falsifies the record to achieve a sense of peace. But the faith that is able to warm itself at the fire of God’s love, instead of having to steal love and self-acceptance from other sources, is actually the root of peace.
Only a fraction of the present body of professing Christians are solidly appropriating the justifying work of Christ in their lives… In their day-to-day existence they rely on their sanctification for justification… Few know enough to start each day with a thoroughgoing stand upon Luther’s platform: you are accepted, looking outward in faith and claiming the wholly alien righteousness of Christ as the only ground for acceptance, relaxing in that quality of trust which will produce increasing sanctification as faith is active in love and gratitude.
