No Undiscovered Lurking-places

On God’s call to Abram (Genesis 12:1) to leave and seek what he could not see:

[I]t is not to be supposed, that God takes a cruel pleasure in the trouble of his servants; but he thus tries all their affections, that he may not leave any lurking-places undiscovered in their hearts.

—John Calvin, Commentary on the First Book of Moses Called Genesis
