John Warr, an 18th-century apprentice shoemaker, was determined to be a faithful witness for Christ. Another apprentice by the name of William was hired, and John repeatedly talked to him about spiritual things, but the new worker didn't want to be bothered. Then one day he was caught exchanging a counterfeit shilling for a good one. In his guilt and humiliation he asked John for help and prayer. Through the faithful witness of John Warr, that man put his faith in Christ and developed into a committed disciple.

The young apprentice was William Carey, who later became a remarkably fruitful missionary to India. Carey's life and ministry had a tremendous influence on the cause of worldwide gospel outreach in modern times.

Jesus said in John 15:8, "By this My Father is glorified, that you bear much fruit." This could be discouraging to Christians who can't preach, sing, teach, or go to the mission field. They might see themselves as stuck in a situation that makes fruitful service impossible.

If that's how you feel, then take courage from the example of John Warr. His impact on a co-worker brought glory to God and untold blessing to multitudes of people around the world.
