Exodus 3:4 - So when the Lord saw that he turned aside to look, God called to him from the midst of the bush and said, “Moses, Moses!” And he said, “Here I am.”
God calls you and has a job for you to do.
What is your response?
Do you run and hide like Jonah?
Do you argue with God about how you're unqualified like Moses?
Do you fear how much what He asks you to do will cost you?
Or do you celebrate?
Does God want our best outcome, or does He like seeing us miserable? Think on it.
Luke 11:11-12 - If a son asks for bread from any father among you, will he give him a stone? Or if he asks for a fish, will he give him a serpent instead of a fish? Or if he asks for an egg, will he offer him a scorpion? 13 If you then, being evil, know how to give good gifts to your children, how much more will your heavenly Father give the Holy Spirit to those who ask Him!”
Why do we consider it an obligation to do what He asks? Why do we fear what He asks of us?
We think we know our future.
If we try, of our own volition, to do anything that God asks us to do - we know we would fail. How soon we forget that He ASKED! If God asked you to free the Israelites from Egypt - He will obviously make it possible for you to do it. If He asks you to witness to someone, He will empower you to withstand any onslaught that might follow. But if Moses tried to free Israel without God's call - he would have failed miserably. So he predicted his own failure when he argued with God.
When God calls you next time, DON'T argue and predict your own failure. Don't consider it an obligation you HAVE to do to make God happy. He is not the one who will get the reward for your obedience - you are. Each call to action is an opportunity for that reward.
We have cause to celebrate when we consider God's call an opportunity, rather than an obligation. He calls us to do these things for our own benefit, not His. Let's remember that, and celebrate when we hear His voice!
