Thinking about various things occupies the greater part of our life. Contemplating worldly things, worrying about the future, dwelling upon the past, being unduly curious about others . . . all these things take up our time. In fact, they keep us away from God. If you want the Lord to uplift you spiritually, ask him to uplift your thoughts too. The time of our life is precious. Any time wasted is time lost forever, the time you could have used for building up treasure in heaven. Seek to attain union with God to have him occupy your mind completely to block out all wasteful thoughts. And I assure you that you'll experience inner peace.
