The correct action

People think that honesty is the best practice. People will speak lies when that person fears the wrath of a person.
Abraham didn't have honest faith in God when he feared that he would die. He had a pretty wife and he feared people.
Abraham knew the correct action but he didn't follow the correct action.
God protected Abraham's wife when Abraham should have protected his wife.
Abraham wasn't the best witness for the Lord.  Abimelek was angry with Abraham.
The follower of Jesus needs to trust in the Lord and be pure before the Lord.

Genesis 20:6-10

 

⁶ Then God said to him in the dream, “Yes, I know you did this with a clear conscience, and so I have kept you from sinning against me. That is why I did not let you touch her. ⁷ Now return the man’s wife, for he is a prophet, and he will pray for you and you will live. But if you do not return her, you may be sure that you and all who belong to you will die.”
⁸ Early the next morning Abimelek summoned all his officials, and when he told them all that had happened, they were very much afraid. ⁹ Then Abimelek called Abraham in and said, “What have you done to us? How have I wronged you that you have brought such great guilt upon me and my kingdom? You have done things to me that should never be done.” ¹⁰ And Abimelek asked Abraham, “What was your reason for doing this?”
