They should seek to cultivate their powers and develop characters that will be meet for a holy heaven. Then and then only will the servants of God be bright and shining lights in the world. Then they will bring energy into their Christian life, for they will put all their powers to the task, and respond to the efforts that have been made to uplift, refine, and purify them, that they may shine in the courts above. They will bring all their powers under the control of the Spirit of God; they will study His Word, and listen for His voice, to direct, encourage, strengthen, and advance them in their religious experience.
