“The Sabbath is a sign of Christ's power to make us holy. And it is given to all whom Christ makes holy. As a sign of His sanctifying power, the Sabbath is given to all who through Christ become a part of the Israel of God....
“The Sabbath points them to the works of creation as an evidence of His mighty power in redemption. While it calls to mind the lost peace of Eden, it tells of peace restored through the Saviour. And every object in nature repeats His invitation, ‘Come unto Me, all ye that labor and are heavy-laden, and I will give you rest.’ Matt. 11:28.”—Ellen G. White, The Desire of Ages, pp. 288, 289.
“Jesus says, ‘Abide in Me.’ These words convey the idea of rest, stability, confidence. Again He invites, ‘Come unto Me, . . . and I will give you rest.’ Matthew 11:28. The words of the psalmist express the same thought: ‘Rest in the Lord, and wait patiently for Him.’ And Isaiah gives the assurance, ‘In quietness and in confidence shall be your strength.’ Psalm 37:7; Isaiah 30:15. This rest is not found in inactivity; for in the Saviour’s invitation the promise of rest is united with the call to labor: ‘Take My yoke upon you: . . . and ye shall find rest.’ Matthew 11:29. The heart that rests most fully upon Christ will be most earnest and active in labor for Him.
“When the mind dwells upon self, it is turned away from Christ, the source of strength and life. Hence it is Satan’s constant effort to keep the attention diverted from the Saviour and thus prevent the union and communion of the soul with Christ. The pleasures of the world, life’s cares and perplexities and sorrows, the faults of others, or your own faults and imperfections—to any or all of these he will seek to divert the mind. Do not be misled by his devices. Many who are really conscientious, and who desire to live for God, he too often leads to dwell upon their own faults and weaknesses, and thus by separating them from Christ he hopes to gain the victory. We should not make self the center and indulge anxiety and fear as to whether we shall be saved. All this turns the soul away from the Source of our strength. Commit the keeping of your soul to God, and trust in Him. Talk and think of Jesus. Let self be lost in Him. Put away all doubt; dismiss your fears. Say with the apostle Paul, ‘I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave Himself for me.’ Galatians 2:20. Rest in God. He is able to keep that which you have committed to Him. If you will leave yourself in His hands, He will bring you off more than conqueror through Him that has loved you.” (Ellen G. White, Steps to Christ (Mountain View, CA: 1892), 70, 71.)
