That's in heaven, my friend, not on earth. Those elders are also wearing white robes and golden crowns (Rev 4:4). Is this what we are to wear when worshipping God? Also, angels don't marry (Matthew 22:30 and Mark 12:25). Does that mean we must refrain from marriage as well? Using Heaven and heavenly creatures as an example of how to worship here on earth is not a good idea. Especially when the descriptions of heaven that we have come from the most symbolic book of the Bible. Besides, those images are borrowed from Old Testament worship as evidenced by Revalation 15:5.Daniel Burbank said:. Revelation 5:8,9 says "Now when He had taken the scroll, the four living creatures and the twenty-four elders fell down before the lamb, each having a harp, and golden bowls full of incense, which are the prayers of the saints. And they sang a new song, saying "You are worthy to take the scroll, and to open its seals, For You were slain..." and so on and so forth. It appears to me that they are praising God in song and using harps as well. Also in revelation, why would trumpets announce seven plagues if God didn't want them? It seems pretty clear to me that there's no evidence against playing musical instruments while worshipping God, especially if it's being done in heaven.
1 Corinthians 4:6 - Now these things, brethren, I have figuratively applied to myself and Apollos for your sakes, so that in us you may learn not to exceed what is written, so that no one of you will become arrogant in behalf of one against the other.
What else is written on this subject besides Ephesians 5:19 and Colosians 3:16?
