"the twenty-four elders fall down before him who sits on the throne and worship him who lives for ever and ever. They lay their crowns before the throne..."
It is fascinating that these twenty four elders, whoever they might be, are given crowns. Whether these are literal crowns (Ps 21:3; Rev 4:4) or crowns of glory (1Pe 5:4) and righteousness for having completed the race (2Tim 4:8) or the crown of life (James 1:12; Rev 2:10) or perhaps even crowns of people ("For what is our hope or joy or crown of boasting before our Lord Jesus at his coming? Is it not you? For you are our glory and joy." 1Th 2:19) it does not matter much. The interesting thing is that these crowns are given so that they may be laid at the feet of He who sits on the throne as an act of worship.
So it is that the earthly realm was made to reflect the heavenly realm where worship is an eternal reality that all things given on earth are to be used to worship God just as it is in heaven. If God has granted you riches, than worship God with riches. If he has given you rags, then worship Him with rags. Worship God with whatever God has given you for those who receive crowns from God are those who are willing to give them back in worship and humility.
