Dedicate completely
"Samuel said to the people of Israel, “If you are going to turn to the LORD with all your hearts, you must get rid of all the foreign gods and the images of the goddess Astarte. Dedicate yourselves completely to the LORD and worship only him, and he will rescue you from the power of the Philistines.”"
~ 1 Samuel 7.3 GNB
Samuel's instruction was specific: turn with all my heart and dedicate myself completely and worship only the LORD. There is no room in the slightest for another. All of me for the LORD.
