And the glory which Thou gavest Me I have given them; that they may be one, even as We are one: I in them, and Thou in Me, that they may be made perfect in one; and that the world may know that Thou hast sent Me, and hast loved them, as Thou hast loved Me. -John 17:22-23

(D)o not be afraid to go out into the world to do good. Christ is keeping you in the world for the advantage of your fellow-men. I am sometimes wicked enough to think that I would rather go anywhere than stand up again and preach my Master’s gospel. Like Jonah, I have thought I would really pay my fare to be carried away to Tarshish, instead of coming back to Nineveh. So would some of you who have tried to preach, and found you could not succeed as you desired. But do not be down-hearted, my brother; a Christian should never get so. If you have but one listener to-day, perhaps the next time the number will be doubled, and so on, till they cannot be counted. Never say, “I wish to go out of this world:” do not murmur, “My life Is prolonged beyond my joys.” Do what you can. Do not go amongst people with fear; do not be ashamed to look duty in the face. If you are not successful at first, do not be cowards and run away from your guns. We should do all we can to bring our guns into line with our brothers, and take good aim at our foes. Never desert your work, though you come home distressed in spirit, though you see no gleam of success, and nothing is gained. Recollect, you cannot run out of the battle, but you must go on; and you cannot escape the service. On, then, and glory shall be yours.~ C.H. Spurgeon
