Walking In The Ways Of God

As iron cast into fire loses its rust and becomes glowing white, so he who turns completely to God is stripped of his sluggishness and changed into a new man. When a man begins to grow lax, he fears a little toil and welcomes external comfort, but when he begins perfectly to conquer himself and to walk bravely in the ways of God, then he thinks those things less difficult which he thought so hard before.

The Imitation Of Christ, Thomas A Kempis
