Galatians 6:9 And let us not be weary in well doing: for in due season we shall reap, if we faint not.
William Wilberforce led a campaign against the British Parliament to abolish slavery in the late 1700's and early 1800's. During the course of his intense efforts, Wilberforce came to a desperate place of discouragement, feeling he had absolutely no more strength to continue. In this condition he was about to give up, when his elderly friend, John Wesley, lying on his deathbed, was informed of his friend William's distress. Wesley requested pen and paper, and with a quivering hand, wrote these words,
"Unless God has raised you up for this very thing, you will be worn out by the opposition of men and devils. But if God be for you, who can be against you? Are all of them stronger than God? Oh be not weary of well-doing! Go on, in the name of God and in the power of his might, till even American slavery shall vanish away before it."
John Wesley died six days later, but William Wilberforce fought for forty-five more years, and in 1833, three days before his own death, witnessed the abolition of slavery in Britain.
Do not grow weary in well-doing, for we can still triumph! It's exactly when everything looks hopeless that our God has opportunity to display His awesome power. Even the great men that changed history needed a word of encouragement now and then – so be encouraged, and be an encourager! You never know when you may enable another saint to continue pressing on, or how that may change the world!
