There is no happiness without holiness. Created in God’s image “to glorify God and to enjoy him forever,” our fulfillment, meaning and pleasure are found in friendship with God. As the church father Augustine expressed it in the form of a prayer, “You have made us for yourself, and our heart is restless until it rests in you.”

Perhaps no doctrine has greater bearing on all other doctrines than the doctrine of God. How we understand the nature and character of God himself influences how we understand the nature of man, who bears God’s image; the nature of Christ, who works to satisfy the Father; the nature of salvation, which is effected by God; the nature of ethics, the norms of which are based on God’s character; and a myriad of other theological considerations, all drawing on our understanding of God.
