There are a number of lessons that can be learned from this very interesting chapter in the Old Testament.
Q: What does Abraham’s half-truth tell us about his trust in the Lord?
A: It tells us that Abraham was still in the process of faith-building. He did not trust the Lord enough to rely solely upon His intervention and protection, and felt that he needed to resort to human tactics to protect himself. His faith was incomplete. It will be completed in chapter 22 when he offers Isaac in sacrifice.
Q: Can you name any instances in which you’ve resorted to half-truths to protect yourself or to gain an advantage? (E.g., in the workplace, concerning financial issues, concerning relationships with the opposite sex?) What does this tell us about our ability to trust God for the outcome?
Q: How does the word “manipulation” fit into the category of half-truth? Why do we tell half-truths instead of the whole truth or plain truth?
A: A half-truth is not an out-and-out lie; therefore, we feel justified. But is that fully trusting God?
Q: What is the point of Abraham’s half-truth to Abimelech?
A: He didn’t need to resort to a half-truth. He could have told the exact truth, that Sarah was his wife. Could God not have protected him? Can God not protect you and grant you the promise of Romans 8:28? “And we know that God causes all things to work together for good to those who love God, to those who are called according to His purpose.”
