In the New Testament, repentance means to change the way that we think and act. Without the Lord, this would be impossible. However, when we bring, and then surrender, our thoughts, beliefs and actions to the Lord, He replaces them with peace, truth and hope. True repentance brings transformation.
I love to work in my garden. Have you ever dug a large hole in hard clay to plant a bush? I think repentance requires many of the same steps.
When I dig the hole, I expend a tremendous amount of energy. Being willing to openly expose my sins and faults to the Lord also requires much effort.
Sometimes my feet hurt from stomping down on the shovel as I try to break through the hard soil. Likewise, there have been times when my body, soul and spirit ache as I struggle and my heart can feel like heavy, solid clay.
