A little girl who loved the Lord longed to share the message of salvation with those who had never heard it. So she contributed a penny to a missionary to help with the work of evangelizing the people of Burma. That small coin was all she had, but it was given from her heart. The worker on the foreign field was deeply touched by the child's earnestness and decided he would do the most he could with the money. After careful thought he purchased a Gospel tract and personally gave it to a young chieftain. Apparently the Christian did not know that the tribal leader was not educated well enough to read it. God instilled within the ruler a burning desire to know the meaning of the leaflet and he traveled 250 miles to find someone who could translate it for him. After he heard the Gospel message, it wasn't long until the young chief was gloriously converted. Returning to his people, he told them what the Lord had done for his soul. Later he invited missionaries to come and preach this and probably much more resulted from one dedicated penny given in Christ's name by a little girl who wanted the lost to hear about Jesus!
Don't wait until you can do "great things" to start working for the Master. God can do wonders with dedicated little things.
