John Piper Friday

"The goal of world missions is the gladness of the peoples in the glory of God. The fuel of that goal is our own gladness in God. If we are not real and deep and fervent in our worship of God, we will not commend him among the peoples with genuineness. How can you say to the nations, "Be glad in God!" if you are not glad in God?"
