Abraham, the great man of faith, did not always act that way. Once, when fearing for his safety, he lied to king Abimelech, claiming that Sarah was his sister and hiding the fact that they were married.
Assured by Abraham’s lie, Abimelech felt free to take Sarah into his harem. Fortunately, God intervened before anything happened to her, revealing the truth of the situation to Abimelech in a dream. God’s instructions to Abimelech were simple: return Sarah to Abraham and then Abraham would pray for Abimelech.
Abimelech quickly returned Sarah as instructed. He also gave many gifts to Abraham, as well as to Sarah. Then Abraham prayed for Abimelech and everything was made right.
What is interesting is that God never told Abimelech to give gifts to Abraham and Sarah. Abimelech did that on his own; God did not require that.
I wonder how many times we act in the same way, doing things that God didn’t ask us to do and that he didn’t require.
