To love God supremely is the fundamental duty of man, as well as the foundation of true salvation, obedience, and Christian living. From John 15:9 and other scriptures, the Bible teaches that Christ loves His people as the Father loves Him, and He told us to "continue in his love." Real love is not merely emotion, religious zeal, loyalty, or words, but a life that gives itself to God in obedience and sacrifice. Love is not love unless it puts to death the selfish, self-centered heart, and esteems God and others more than ourselves. Do not be deceived by your emotional feelings toward God if you are living in disobedience to his Word. Love lives only in deeds, and the kind of love God commands from us is not feelings and emotion, but recognizing his greatness and goodness and laying down our lives for Him.
