What we think, we are. "For as he thinketh in his heart, so is he... (Proverbs 23:7).
Dwelling on negatives can destroy us. The person who constantly thinks about problems and approaching disasters courts unhappiness. He chooses to be miserable. Focusing his attention on trouble, he is always troubled. His mind becomes fixed on gloom, and it is not strange that his general mood is gloomy.
Those who prefer to meditate on misery are like Eve, occupied with one tree of fruit that was marked for death while surrounded with untold varieties of allowable lifegiving choices. And when one lingers at the forbidden place, the tempter is always nearby.
The Bible calls us to a life centered in God's blessings. Why choose error when truth is better? To ignore the wrongs in the world is head-in-the-sand thinking. To make those wrongs the constant meditation of our hearts is an even greater mistake.
All great revivals have produced joyful Christians. The reason? Christ has become the focal point of thought and action. He is the One who is true, honest, just, pure, lovely and of good report. He personifies virtue and is always worthy of our praise.
Think on Jesus.
