From Power in the Name of Jesus by Jennifer Kennedy dean
In the context of your present circumstances, God’s name is a present-tense name. Not I WAS. Not I WILL BE. His name is always I AM.
Do you see that by telling you that His name is I AM it changes the center of gravity of the whole relationship? Everything tips in His direction. The burdens, the expectations, the pressure to perform, the disappointments all roll off your shoulders and land at His feet. Everything changes for you when you have encountered your I AM.
