The self-sacrificing servants of God do not measure their work by hours. Their wages do not influence them in their efforts. They have received their commission from heaven, and to heaven they look for their reward. ULe 131.2
Such workers should be freed from unnecessary cares. While they should be careful to exercise to keep the mind and body vigorous, yet they should not have to spend a large part of their time at secular employment. These faithful workers are not immune to temptation. When burdened with worry because the church has failed to give them proper financial support, some are fiercely attacked by the tempter. They become depressed. Their families must have food and clothing. If they could feel released from their divine commission, they would be willing to labor with their hands. But they realize that their time belongs to God, and they continue to advance the cause that is dearer than life itself to them. However, for a while they may be forced to engage in manual labor while doing ministerial work. ULe 131.3
Sometimes because of lack of funds it seems impossible to do the work that needs to be done. Some people fear that they cannot do everything that they feel is their duty. But if they move forward in faith, success will follow their efforts. Jesus, who has asked His followers to go into all the world, will sustain every worker who tries to proclaim His message. ULe 131.4
In the building up of His work, the Lord sometimes tests the confidence of His people by bringing about circumstances that compel them to move forward in faith. Often He tells them to advance when their feet seem to be touching the waters of Jordan. (See Joshua 3:14-17.) At such times, when their prayers go up to Him in earnest faith, God opens the way before them and blesses their efforts beyond their expectations. Angels will prepare the way before them, and the funds necessary for the work will be provided. Those whom God has enlightened will give freely to support the work. The Spirit of God will move on their hearts to maintain the Lord’s cause, not only in home fields, but in the regions beyond. And so the work of the Lord will advance in His own appointed way.
