The Bridal Gown
The bride is dressed in the righteousness of Christ and the corresponding righteous acts that she has done:
“Fine linen, bright and clean, was given her to wear.”
Fine linen stands for the righteous acts of God’s people (see Revelation 19:8).
This clothing is distinguished from Babylon’s by being bright and clean.
And there seems to be a language connection between the dress of the bride and the qualities of the New Jerusalem.
The bride of Jesus and the New Jerusalem are mentioned as the same entity when God’s people are living in it.
“Righteous acts” is a special term (see Revelation 15:4). It is not the forensic, legal, righteousness noted by Paul in Romans 5:18.
In the Old Testament, a righteous act is one that functions in harmony with the covenant. They are correct according to the laws of God or society.
In Romans, Christ did what was right. His righteous acts can be imputed to His people so His people, are accounted legally as Christ.
There is an intimate connection between God’s faithfulness and that of His people. The imputed righteousness of Christ would be that which is placed on them but the wedding garment is the righteous actions they have done.
