He will use you and me and each human being who enters His service, if we will submit to His guidance. Each one is to stand in his watchtower, listening attentively to that which the Spirit has to say to him, remembering that his every word and act makes an impression, not only on his own character, but on the characters of those with whom he is connected....
Each day God works with His building, stroke upon stroke, to perfect the structure, that it may become a holy temple for Him. Man is to co-operate with God. Each worker is to become just what God designs him to be, building his life with pure, noble deeds, that in the end his character may be a symmetrical structure, a fair temple, honored by God and man. There is to be no flaw in the building, for it is the Lord’s. Every stone must be perfectly laid, that it may endure the pressure placed upon it. One stone laid wrong will affect the whole building. To you and to every other worker God gives the warning: “Take heed how you build, that your building may stand the test of storm and tempest, because it is founded on the eternal Rock.”—Testimonies for the Church 8:172, 173.
To every man is given “his work“—the work for which his capabilities adapt him—the work which will result in greatest good to himself and to his fellow-men, and in greatest honor to God.
Thus our business or calling is a part of God’s great plan, and, so long as it is conducted in accordance with His will, He Himself is responsible for the results.—Education, 138. WGD 282
In ministering to the sick, more than in any merely secular business, success depends on the spirit of consecration and self-sacrifice with which the work is done. Those who bear responsibilities need to place themselves where they will be deeply impressed by the Spirit of God. You should have as much greater anxiety than do others for the aid of the Holy Spirit and for a knowledge of God as your position of trust is more responsible than that of others. MH 511
For we are labourers together with God: ye are God’s husbandry, ye are God’s building. 1 Corinthians 3:9, KJV
