Worship

Worship is the proper response of all moral, sentient beings to God, ascribing all honor and worth to their Creator-God precisely because he is worthy, delightfully so. This side of the Fall, human worship of God properly responds to the redemptive provisions that God has graciously made. While all true worship is God-centered, Christian worship is no less Christ-centered. Empowered by the Spirit and in line with the stipulations of the new covenant, it manifests itself in all our living, finding its impulse in the gospel, which restores our relationship with our Redeemer-God and therefore also with our fellow image-bearers, our co-worshippers. Such worship therefore manifests itself both in adoration and action, both in the individual believer and in corporate worship, which is worship offered up in the context of the body of believers, who strive to align all the forms of the devout ascription of all worth to God with the panoply of new covenant mandates and examples that bring to fulfillment the glories of antecedent revelation and anticipate the consummation.
D. A. Carson Worship by the Book (pg. 26)

The great multitude in Revelation which no man can number aren’t playing cricket. They aren’t going shopping. They are worshipping. Sounds boring? If so, it shows how impoverished our idea of worship has become. At the centre of that worship stands a passage like Isaiah 33: your eyes will see the king in his beauty; the LORD is our judge, the LORD is our ruler, the LORD is our king; he will save us. Worship is the central characteristic of the heavenly life; and that worship is focues on the God we know in and as Jesus.
N. T. Wright For All God’s Worth (pg. 7)

This is, indeed the proper business of the whole life, in which men should daily exercise themselves, to consider the infinite goodness, justice, power and wisdom of God, in this magnificent theatre of God.
John Calvin
