Maybe it's time to switch meals. We often don't hunger for righteousness because we have filled up on the wrong stuff. Jesus promises a meal that will satisfy completely.
When you received Christ, He gave you a new heart. But sometimes we allow things to "mix in" and contaminate that purity. Learn how to stay pure in heart.
We must finally come to the realization that we are completely destitute without Jesus. When we understand that truth, we can be fully surrendered to anything He leads us to accomplish for His Kingdom.
