At the age of twenty-seven, he dedicated all his resources and energies to the cause of Christ, writing the dedication in his own blood. “God graciously called me,” he says, “out of the world, and granted me the desire to belong to Him, and 133 / 103 to be willing to follow Him.” He gave up secular employments altogether, and devoted his whole time to religious instruction and to the poor. His house became famous as the “Pilgrims' Cottage,” and was visited by people high and humble from all parts of Germany. In his lifetime he is said to have written one hundred and eleven hymns. Died April 3, 1769.

God calling yet! shall I not hear?

Earth's pleasures shall I still hold dear?

Shall life's swift-passing years all fly,

And still my soul in slumber lie?

* * * * * *

God calling yet! I cannot stay;

My heart I yield without delay.

Vain world, farewell; from thee I part;

The voice of God hath reached my heart.
