Thomas is known almost entirely for composing or compiling a manual of spiritual advice known as The Imitation of Christ, in which he urges the reader to seek to follow the example of Jesus Christ and to be conformed in all things to His will. An extract follows:
When God bestows Spiritual comfort, receive it with a grateful heart; but remember that it comes of God's free gift, and not of your own merit. Do not be proud, nor over joyful, nor foolishly presumptuous; rather, be the more humble for this gift, more cautious, and more prudent in all your doings, for this hour will pass, and temptation will follow it. When comfort is withdrawn, do not immediately despair, but humbly and patiently await the will of Heaven; for God is able to restore you to a consolation even richer than before. This is nothing new or strange to those who know the ways of God, for the great Saints and Prophets of old often experienced these changes. ...Indeed, the temptation that precedes is often a sign of comfort to follow. For heavenly comfort is promised to those who have been tried and tempted."To him who overcomes," says God, "I will give to eat of the Tree of Life."
