Abraham believed Abimelech was not to be trusted so he lied and said Sarah was his sister instead of his wife. God saved Abimelech from getting himself into trouble; however, and Abimelech ended up giving Abraham land, money, and livestock. Then Abraham prayed for Abimelech and the people were healed from infertility that had occurred from this situation.
It was one thing to distrust Abimelech, but distrust of a person should never lead to a distrust of God. Abraham was promised great blessings from God. He was promised blessing, land, and descendants. But when this situation arose, Abraham’s distrust of Abimelech caused Abraham to react in a way that doesn’t give God the chance to act in His way.
We can distrust others, but faith in God and His plan should still be intact. We don’t always understand situations, but we can trust that God is working through each situation.
“Trust in the LORD with all your heart and lean not on your own understanding.” – Proverbs 3:5 [NIV]
