From "Imitation of Christ"

He who seeks anything but God alone and the salvation of his soul will find only trouble and grief, and he who does not try to become the least, the servant of all, cannot remain at peace for long.

You have come to serve, not to rule. You must understand, too, that you have been called to suffer and to work, not to idle and gossip away your time. Here men are tried as gold in a furnace. Here no man can remain unless he desires with all his heart to humble himself before God.
