Desires grow because of being fed.

Desires grow because they are fed. Therefore, desires that are big in our lives are there because we have fed them. Desires that are minimal in our lives are in their condition not by accident but because we have neglected them. If prayer is neglected then the desire for Christ will become minimal. This is why people who are truly so in love w/ Christ are a praying people... they are feeding it. Never say "I wish I had that kind of desire..." Do what that person does and you will have what they have.
