When I first entered Christianity, I prayed more than I do today and that is a good thing. Most of my praying consisted of telling God what was going on in my life and the world around me and then telling him how to fix the problems. Such arrogance is appalling. What could I tell God that he doesn’t already know? Fortunately, his mercy is new every morning.
I don’t pray as much today because I have stopped telling God what he already knows. God knows what happened in the past. He was there. He knows what is going on in our lives. He has placed his Spirit within us. He knows what will happen tomorrow. He decides what will happen and then makes it happen.
In God’s dealings with Abraham he said “I know” three times. Two times in reference to Abraham and once to calm the fear of a king that Abraham had lied to. Each time God’s actions were based on what he “knows” that no one had to tell him.
When God was on his way to judge Sodom and Gomorrah, he stopped at Abraham’s tent to reveal his plans. There was a reason God told Abraham about the coming judgment. God said,
“I know him [Abraham] that he will command his children and his household after him and they shall keep the way of the Lord, to do justice and judgment; that the Lord may bring on Abraham that which he hath spoken of him.
Preserving the knowledge of God’s way by teaching our children is important to God. God’s plan would take generations to fulfill. Therefore, it was important that Abraham teach his children the way of the Lord, so his children would teach their children and that practice would continue until the time came for the fulfillment of God’s promises.
God knew the good that was in Abraham but he also knew the bad. He did not punish Abraham for lying to Pharaoh and to King Abimelech, but he did expose him. We don’t know how Pharaoh learned Abraham lied to him. We do know how King Abimelech discovered the truth. God told him. He appeared to Abimelech in a dream and said, “You are as good as dead because of the woman you have taken; she is a married woman.”
Abimelech told God what he already knew. Abraham lied to him. Abimelech had a clear conscience and clean hands. His innocence did not change the fact that Sarah was a married woman and taking her into his bed would have been a sin against God worthy of the death penalty. God told Abimelech the truth because he did not want him to perish.
God’s response to the problem Abraham’s lie created tells us a lot about God. He knew Abimelech was free of malicious intent, so he kept Abimelech from sin. Now that Abimelech knows the truth, he must do the right thing or he will die. Not only must he return Sarah to her husband. Abimelech must ask the liar who got him into this mess to pray for him so he will live. If Abimelech had been an arrogant man he would have died.
Neither the good nor the bad in Abraham moved God to favor him. The promises God made to him were not guaranteed until God swore an oath to keep them. God swore that oath when Abraham obeyed God to offer Isaac as a sacrifice. Abraham’s actions confirmed what God already knew.
“Now I know that you fear God seeing you have not withheld your son, your only son from me.”
If Abraham had not feared God he might have lost everything God promised to him and we would be calling someone else the father of our faith.
