We are a people of God, made by and made for God. God created us for himself. We are to manifest the glory of God. We are to show forth the purpose of God in all creation. We are here just to reflect the beauty of God.
The will of God is in his commandments. The word of God reveals what God wants from us. To know what a person wish, one must listen to the words of that person. The word of God reveals to us that purpose of God. To be useful in the sight of God, we must learn to be obedient to his word.
Neglecting the instructions of God will not do good to anyone. Refusing to obey the doctrines of Jesus Christ is refusal to do the will of God. The will of God is contained in the commandments of God for our lives. Being obedient to God is what we must strive to do. And to achieve that, we must obey what the Bible teaches us.
