The law is to govern and guide the thinking of Joshua and Israel. Consistent study of law is required since human memory is frail and forgetful so that one’s way is shaped in a manner that pleases God.1 Life in the kingdom of God must be lived from the Word of God. Life pleasing to God does not come from warm feelings or mystical experiences but practical knowledge and obedience.2 We see the same truth in Psalm 1:1–6.
7 Only be strong and very courageous, being careful to do according to all the law that Moses my servant commanded you. Do not turn from it to the right hand or to the left, that you may have good success wherever you go.
