A Rock In My Shoe. That person that causes you to stumble into fear, unbelief, anger, and a plethora of uncontrolled emotions should not be able to have that much power over you. The reason I use the analogy of a rock is because rocks are hard and heavy and the foundation of most things. But our foundation and strength is God. 2 Samuel 22:47 The LORD lives and blessed be my Rock! And may God, the Rock of my salvation, be exalted.
