The Lord has given every man his work. It is his business to do it, and the devil's business to hinder him if he can. And as sure as God has given you a work to do, Satan will try to hinder you.
My dear Christian friend, keep at your work. Do not flinch because the lion roars; do no stop to stone the devil's dogs; do no fool away your time chasing the devil's rabbits. Do your work. Let liars lie, let religious sectarians quarrel, let corporations resolve, let editors publish, and come what may, let the devil do his worst; but see to it that nothing hinders you from fulfilling the work God has given you.
Keep at your work. Let your aim be as steady as a star. Let the world brawl and babble and bubble. Keep at your work. You may be assaulted, wronged, insulted, slandered, wounded and rejected; you may be abused by foes, forsaken by friends and despised and rejected of men, but see to it with steadfast determination, with unfaltering zeal, that you pursue the great purpose of your life and the object of your being, until at last you can say, "I have run the race...I have finished the work which thou gavest me to do."
