and beneficial thoughts for one's life in pursuit of union with God:

"True self-knowledge makes you aware of your own worthlessness and you will take no pleasure in the praises of others. If your knowledge encompasses the universe and the love of God is not in you, what good will it do you in God's sight? He will judge you according to your actions."
Part of my slow and often-thwarted attempts to become closer to God is to meditate on the 'instructions' given in Thomas A Kempis'
The Imitation of Christ. As I find things that interest me I'll probably post them here. This quotation here is of an interesting paragraph.
There are more paragraphs similar to this one. The problem is that they are directed to people who already have a good self-image. The author isn't suggesting that you develop a bad self-image but rather that you temper it with reality. The problem that besets a person with a poor self-image is that they try to justify their bad self-image by this recommendation. They're still not seeing reality.
(Anyone who knows me will know that this knowledge is all intellect. My self-image is as poor as anyone's and this chapter doesn't do me a bit of good.)
