When the LORD saw that he had gone over to look, God called to him from within the bush, “Moses! Moses!”And Moses said, “Here I am.” Exodus 3:4 “Here I am” –best place to start
Jacob (Genesis 31:11) Samuel (1 Samuel 3:4) Isaiah (Isaiah 6:8)
God calls you at the right time
The LORD said, “I have indeed seen the misery of my people in Egypt. I have heard them crying out because of their slave drivers, and I am concerned about their suffering. So I have come down to rescue them from the hand of the Egyptians and to bring them up out of that land into a good and spacious land,a land flowing with milk and honey... And now the cry of the Israelites has reached me, and I have seen the way the Egyptians are oppressing them. So now, go. I am sending you to Pharaoh to bring my people the Israelites out of Egypt.” Exodus 3:7-10
“Why me?” “Why now?” …Why not?
But Moses said to God, “Who am I that I should go to Pharaoh and bring the Israelites out of Egypt?” Exodus 3:11
