Why is it so important for us to be still anyway? Doesn't God want us to be productive? Yes, He does, but not to the extent that we lose our focus. God wants us to take some time to rest and to dwell on the fact that He is God. In other words: He is our Creator. He is our Helper. He is our Salvation. He is our King. He is our Friend. He is our Comforter. He is our Hope. He is our Counselor. To sum it all up, He is ALL we need.
If I'll just be still long enough to let that sink in, my life will be forever changed. "Be still, and know that I am God." It's not just a command. It's a necessity of life!
