Our heart condition determines how we perceive life. Yet, how do we have a “happy heart?” David knew something about this. When life circumstances turned from bad to worse around him, the Bible says that he “encouraged himself in the Lord” (1 Sam. 30:6 KJV). His circumstances didn’t immediately change, but his heart did. And when our heart changes, we see possibilities rather than limitations. Is your life full of trouble or like a continual feast? Perhaps it’s more a matter of your heart than your circumstances.
