Revelation 4:9-11; Worship In Heaven

Revelation 4:9-11 And when those beasts give glory and honour and thanks to him that sat on the throne, who liveth for ever and ever, 10 The four and twenty elders fall down before him that sat on the throne, and worship him that liveth for ever and ever, and cast their crowns before the throne, saying, 11 Thou art worthy, O Lord, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created. 

Giving glory and honour and thanksgiving to God was the theme of worship in heaven.
