"Do you know that joy? Some persons think that there is great joy in material possessions, but things in themselves do not satisfy. Others think that there is joy in worldly fame, achievement, or pleasure, but these goals are relatively unrewarding. They satisfy at best for a short time. Real joy comes in being able to say to Jesus Christ, "Here I am, Lord, use me," and then finding that out of His grace He is able to use you to bring others into a saving relationship to Himself."
~ James Montgomery Boice, (Th.D. was a reformed theologian, Bible teacher, and pastor of Tenth Presbyterian Church in Philadelphia from 1968 until his death)
