Ellen White on Law and Grace

He who is trying to reach heaven by his own works in keeping the law, is attempting an impossibility. Man cannot be saved without obedience, but his works should not be of himself; Christ should work in him to will and to do of his good pleasure. If a man could save himself by his own works, he might have something in himself in which to rejoice. The effort that man makes in his own strength to obtain salvation, is represented by the offering of Cain. All that man can do without Christ is polluted with selfishness and sin; but that which is wrought through faith is acceptable to God. When we seek to gain heaven through the merits of Christ, the soul makes progress. Looking unto Jesus, the author and finisher of our faith, we may go on from strength, from victory to victory; for through Christ the grace of God has worked out our complete salvation.
