Obedience, faith, and trust. God knows best because he is the creator and not the creation. God knows the future. God is the one who has the plan of salvation. Thus walking with God in obedience, faith, and trust gives us the blessings of God mentioned in Deuteronomy 11. His path is always the right one when we walk with God.
