What does it mean “to have an eye single to the glory of God”?
“To have an eye single to the glory of God means to have singleness of purpose, to show forth the work that has been wrought in your heart, that subdues your will to the will of God, and brings into captivity every thought to the glory of God. … What testimony have you borne in your daily life and character? God expected you all to do your best, not to please, amuse, and glorify yourselves, but to honor Him in all your ways, returning unto Him according to the light and privileges that He had given you through the endowment of His grace. He expected you to testify before heavenly intelligences, and to be living witnesses to the world, of the power of the grace of Christ. The Lord tested you, to see if you would treat His rich blessing as a cheap, light matter, or regard it as a rich treasure to be handled with reverent awe. If all had treated the gift of God in this manner—for the work was of God,—then, according to the measure of each one’s responsibility, the grace given would have been doubled, as were the talents of him who traded diligently with his lord’s money.” The Review and Herald, February 6, 1894
