The Lord your God you shall follow, him alone you shall fear, his commandments you shall keep, his voice you shall obey, him you shall serve, and to him you shall hold fast.
It is the Lord, your God, whom you are to follow. You must fear him and observe his commandments and obey what he tells you and serve him and hold fast to him.
And it is impossible to please God without faith. Anyone who wants to come to him must believe that God exists and that he rewards those who sincerely seek him.
