The following is an excerpt from
The MacArthur New Testament Commentary on Revelation 21.
“And the street of the city was pure gold, like transparent glass. I saw no temple in it, for the Lord God the Almighty and the Lamb are its temple.” (Revelation 21:21–22)
As if just seeing the magnificent capital city of heaven from a distance was not privilege enough, John’s angelic guide took him inside. As he entered the city, the apostle noted that the street of the city was pure gold, like transparent glass. The streets in the New Jerusalem were made of the highest quality pure gold which, like everything else in the heavenly city, was transparent like glass. Translucent gold is not a material familiar to us on this earth. But everything there is transparent to let the light of God’s glory blaze unrestricted.
Once inside the city, the first thing John noted was that there was no temple in it. Up to this point, there has been a temple in heaven (cf. 7:15; 11:19; 14:15, 17; 15:5–8; 16:1, 17). But there will be no need for a temple in the new Jerusalem, for the Lord God the Almighty and the Lamb are its temple. Their blazing glory will fill the new heaven and the new earth, and there will be no need for anyone to go anywhere to worship God. Life will be worship and worship will be life. Believers will be constantly in His presence (cf. 21:3); there will never be a moment when they are not in perfect, holy communion with the Lord God the Almighty and the Lamb. Thus, there will be no need to go to a temple, cathedral, church, chapel, or any other house of worship. Believers will be the true worshipers God has always sought (John 4:23).
