I think God is trying to communicate to us all the time...
Exodus 3:1-3 Now Moses was tending the flock of Jethro his father-in-law, the priest of Midian, and he led the flock to the far side of the desert and came to Horeb, the mountain of God. There the angel of the LORD appeared to him in flames of fire from within a bush. Moses saw that though the bush was on fire it did not burn up. So Moses thought, "I will go over and see this strange sight—why the bush does not burn up."
God appears to us through the everyday.
4 When the LORD saw that he had gone over to look, God called to him from within the bush, God saw an opportunity to talk to Moses, because Moses was open to it. God needs us to be open to hear what he has to say. "Moses! Moses!" And Moses said, "Here I am." "Do not come any closer," God said. "Take off your sandals, for the place where you are standing is holy ground."
There is a change that has to occur in us, if we want to hear God speak: Respect, submission, trust, vulnerability, fear...
Exodus 3:7-10 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—the home of the Canaanites, Hittites, Amorites, Perizzites, Hivites and Jebusites. 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."
God always calls us to do something.
We could stop just after we pray, just after we hear God’s voice, just after we take off our sandals. But that’s not the point... The point is that we live in the centre of God’s will and we do that following him.
