Only the man who follows the command of Jesus single-mindedly, and unresistingly lets his yoke rest upon him, finds his burden easy, and under its gentle pressure receives the power to persevere in the right way. The command of Jesus is hard, unutterably hard, for those who try to resist it. But for those who willingly submit, the yoke is easy, and the burden is light.
Dietrich Bonhoeffer, The Cost of Discipleship
