I asked the preacher for a Bible verse that was on his heart, this is what he read to me:
And Moses said unto God, behold, when I come unto the children of Israel, and shall say unto them, the God of your fathers hath sent me unto you; and they shall say to me, what is His name? What shall I say to them?
And God said unto Moses, I AM THAT I AM: and He said, thus shalt thou say unto the children of Israel, I AM hath sent me unto you.
Exodus 3: 13-14
It is good to know who God is.
