10/11 Deuteronomy 10:12-13
12 “And now, Israel, what does the LORD your God require of you? He requires only that you fear the LORD your God, and live in a way that pleases him, and love him and serve him with all your heart and soul. 13 And you must always obey the LORD ’s commands and decrees that I am giving you today for your own good.
Obedience results in relationship. If I obey the Lord in doing what He says I will grow in my relationship with Him and get to know Him better every day. If I do my own thing and trivialize my need for obedience I will not grow and become more like Jesus. He is Lord.
