Then Moses said to God, "Behold, I am going to the sons of Israel, and I will say to them, 'The God of your fathers has sent me to you.' Now they may say to me, 'What is His name?' What shall I say to them?" God said to Moses, "I AM THAT I AM"; and He said, "Thus you shall say to the sons of Israel, 'I AM has sent me to you.'" (Exodus 3:13-14)
God called Moses to bring revival to the Children of Israel who were living in a pagan nation. The Egyptians gave names to their many gods that typified the nature of each particular god. The children of Israel being enslaved for many generations would have been heavily influenced by the deity-driven culture that surrounded them and would perhaps be confused by Moses’ claim to be sent by the God of their fathers. “Which god is that?” they would likely ask. Moses spoke to them the words “I AM WHO I AM”, which in Hebrew are haw-yaw 'ăsher 'haw-yaw' and can be transliterated into the modern-day English “I WILL BECOME THAT WHICH I BECOME”. In effect, God was telling Moses that He (God) would transcend any situation and become the only God needed for all times.
But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me. (II Corinthians 12:9)
The words that Jehovah God said to Moses, “I WILL BECOME THAT WHICH I BECOME” speaks true to your and my generation today. God is not a lofty God who may become distracted with some pursuit, or need to evolve to accommodate us, or has changed His eternal will and purposes toward us. God knows your frame that it is dust (Psalms 103:14). It is in the moments of your weakness and lack of power that you can go to the all-powerful unchanging and everlasting God and realize that you have an eternal God who will become that which you need today and every day.
