What is it like to serve God in His mission? Is it a life of drudgery, hard work, suffering, misery?
Life's deepest satisfaction is found in serving God. God has put something in humans that is only satisfied through service.
I say to you that likewise there will be more joy in heaven over one sinner who repents than over ninety-nine just persons who need no repentance. (Luke 15:7)
Likewise, I say to you, there is joy in the presence of the angels of God over one sinner who repents.“ (Luke 15:10)
But the father said to his servants, 'Bring out the best robe and put it on him, and put a ring on his hand and sandals on his feet. And bring the fatted calf here and kill it, and let us eat and be merry; for this my son was dead and is alive again; he was lost and is found.' And they began to be merry. (Luke 15:22-24)
The Lord your God in your midst, The Mighty One, will save; He will rejoice over you with gladness, He will quiet you with His love, He will rejoice over you with singing.” (Zephaniah 3:17)
looking unto Jesus, the author and finisher of our faith, who for the joy that was set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God. (Hebrews 12:2)
It is wonderful how strong a weak man may become through faith in the power of God, how decided his efforts, how prolific of great results. The hesitating and irresolute, through exercising his abilities in the cause of God, becomes firm and decided. Taking in the great fact that he is called by the Redeemer of the world to work with him for the salvation of men, he dedicates his life to the work. His nature becomes exalted; the mission of Christ opens before him with new importance and glory, and with deep humility he recognizes in himself a co-laborer with the Saviour. No higher office is given to man. No joy can equal the assurance of being an instrument in the hand of God for saving souls. It is a grand thing to look back upon a course of labor all marked with glorious results; to see precious souls progressing in the light through your efforts; to feel that God has worked with and through you in the harvest-field of the world. GW92 359.3
I have been shown that the publications already have been doing a work upon some minds in other countries, in breaking down the walls of prejudice and superstition. I was shown men and women studying with intense interest papers and a few pages of tracts upon present truth. They would read the evidences so wonderful and new to them and would open their Bibles with a deep and new interest, as subjects of truth that had been dark to them were made plain, especially the light in regard to the Sabbath of the fourth commandment. As they searched the Scriptures to see if these things were so, a new light shone upon their understanding, for angels were hovering over them and impressing their minds with the truths contained in the publications they had been reading. I saw them holding papers and tracts in one hand, and the Bible in the other, while their cheeks were wet with tears, and bowing before God in earnest, humble prayer, to be guided into all truth,—the very thing he was doing for them before they called upon him. And when the truth was received in their hearts, and they saw the harmonious chain of truth, the Bible was to them a new book; they hugged it to their hearts with grateful joy, while their countenances were all aglow with happiness and holy joy. These were not satisfied with merely enjoying the light themselves, and they began to work for others. Some made great sacrifices for the truth’s sake and to help those of the brethren who were in darkness. The way is thus preparing to do a great work in the distribution of tracts and papers in other languages. TrueMiss January 1, 1874, par. 16
In a lecture to a large audience at Cambridge on December 4, 1857, David Livingstone spoke of his travels and discoveries in Africa. Here is part of his appeal for missionaries.
For my own part, I have never ceased to rejoice that God has appointed me to such an office. People talk of the sacrifice I have made in spending so much of my life in Africa. Can that be called a sacrifice which is simply paid back as a small part of a great debt owing to our God, which we can never repay ? Is that a sacrifice which brings its own blest reward in healthful activity, the consciousness of doing good, peace of mind, and a bright hope of a glorious destiny hereafter ? Away with the word in such a view, and with such a thought ! It is emphatically no sacrifice. Say rather it is a privilege. Anxiety, sickness, suffering, or danger, now and then, with a foregoing of the common conveniences and charities of this life, may make us pause, and cause the spirit to waver, and the soul to sink ; but let this only be for a moment. All these are nothing when compared with the glory which shall hereafter be revealed in, and for, us. I never made a sacrifice. Of this we ought not to talk, when we remember the great sacrifice which He made who left His Father's throne on high to give Himself for us ; ' who being the brightness of that Father's glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high.1)
