Worship in the Bible is the due response of rational creatures to the self-revelation of their Creator. It is an honoring and glorifying of God by gratefully offering back to Him all the good gifts, and all the knowledge of his greatness and gracious-ness, that He has given. It involves praising Him for what He is, thanking Him for what He has done, desiring Him to get Himself more glory by further acts of mercy, judgment, and power, and trusting Him with our concern for our own and others’ well-being. . . . As worship will be central in heaven (Rev 4:8-11, 5:9-14), so it must be central in the life of the church on earth, and it should already be the main activity, both private and corporate, in each believer’s life (Col 3:17).
—J. I. Packer, Concise Theology, 98-99
