God’s greatest joy is in blessing others. Satan knows this and does all He can to interpose anything between us and those blessings. He uses many things but the tool He uses with the greatest success, the tool he used with Eve there in the Garden of Eden was DOUBT! Satan knows he can’t tear us away from God. There is no force he can use to compel us to throw away God’s blessings. So he most successfully uses doubt to get us to let go of God’s love of our own choice.
