Christ calls us to be His representatives, working untiringly to save lost souls. It is only through unreserved surrender to Him that this will be accomplished. Reference: E.G. White, "The Upward Look," p. 235.

Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. Matthew 11:29.

Those who would at last be received into heaven as members of the royal family must here give themselves, body, soul, and spirit, to the service of Him who paid the price of their redemption. All that we have and are belongs to the Lord. “Ye are not your own,” the apostle declares. “For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s” (1 Corinthians 6:19, 20)...

Have you consecrated yourself wholly to the Lord? Can He use you as a vessel unto honor? Are you faithfully acting your part in His cause? To every man God has given his work. He expects every believer to cooperate with Him in the work of soul-saving. When His cause is suffering for means, how can anyone set a price on his services, refusing to take up the cross daily, and practice self-denial for Christ’s sake?

The fulfillment of the promise that we shall be joint-heirs with Christ rests upon our willingness to deny self. When Christ takes possession of His kingdom, it will be those who on this earth have followed Him in self-denial and sacrifice who will receive the reward of everlasting life.

Christ’s call to sacrifice and unreserved surrender means crucifixion of self. In order to obey this call, we must have unquestioning faith in Him as the perfect Example, and we must have a clear realization that we are to represent Him to the world. Those who work for Christ are to work in His lines. They are to live His life. His call to unreserved surrender is to be to them supreme. They are to allow no earthly tie or interest to prevent them from giving Him the homage of their hearts and the service of their lives. Earnestly and untiringly they are to labor with God to save perishing souls from the power of the tempter.

Those who are thus connected with Christ learn constantly of Him, passing through the successive stages of progress in Christian experience. Difficulty and perplexity come to them, that they may learn more perfectly the will and way of Christ. But they pray and believe, and by exercise their faith increases.

“Take my yoke upon you,” Christ said, as in human nature He lived and worked upon this earth. Constantly He wore the yoke of submission, meeting the difficulties that human beings must meet, bearing the trials that they must bear. The enemy will continually assault us as he assaulted Christ, bringing against us strong temptation. But for everyone there is a way of escape.—Manuscript 88, August 9, 1903, “Be Not Weary in Well-doing.”
