There are two different kinds of garments a believer can wear.
Isaiah wrote by THE SPIRIT in chapter 61:
10 I will greatly rejoice in the LORD, My soul shall be joyful in my God; For He has clothed me with the garments of salvation, He has covered me with the robe of righteousness, As a bridegroom decks himself with ornaments, And as a bride adorns herself with her jewels.
This is our external garment without spot or wrinkle. The second garment and the one that Christ requires for the Marriage festivities is the white linen garment made up of the believer’s own “righteous works” which was expressed in Revelation 19:7–8.
Paul wrote by The Holy Spirit in 2nd Corinthians chapter 7:
1 Therefore, having these promises, Beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting Holiness in the Fear of God.
And in 2nd Corinthians chapter 11:
2 You need to know that God’s passion is burning inside me for you, because, like a Loving father, I have betrothed you (pledged your hand) in marriage to Christ, your True Bridegroom. I’ve also promised that I would present his fiancée to Him as a pure virgin bride.
Overcomers will be clothed in clean, white garments. This speaks of the internal sanctification and the moral fitness that Christ requires of His bride. This second garment, then, is the one that can get defiled, stained, and blackened through the believer’s own negligence. Paul had a serious corrective interview with the Corinthian church concerning their immaturity and the need to move toward walking as mature saints based on Agape Love.
This second garment is one of our righteousness, Holiness, and Fear of The Lord.
Jesus spoke a warning to the dead church in Revelation chapter 3:
1 Write the following to the messenger of the congregation in Sardis, for these are the Words of the One who holds the seven Spirits of God and the seven stars: I know all that you do and I know that you have a reputation for being really “alive,” but you’re actually dead!
2 Wake up and strengthen all that remains before it dies, for I haven’t found your works to be perfect in the sight of My God.
3 So remember all the things you’ve received and heard, then turn back to God and obey them. For if you continue to slumber, I will come to you like a thief, and you’ll have no idea at what hour I will come.
4 Yet there are still a few in Sardis who have remained pure, and they will walk in fellowship with Me in brilliant light, for they are worthy.
5 And the one who experiences victory will be dressed in white robes and I will never, no never erase your name from the Book of Life. I will acknowledge your name before My Father and His angels.
6 So the one whose heart is open let him listen carefully to what the Spirit is now saying to all the churches.
This is a warning to all of us!
James wrote by The Holy Spirit in his Epistle, chapter 1:
27 True spirituality that is pure in the Eyes of our Father God is to make a difference in the lives of the orphans, and widows in their troubles, and to refuse to be corrupted by the world’s values.
Jesus spoke in Revelation chapter 16:
15 “Behold, I come like a thief! God’s blessing is with the one who remains awake and fully clothed in me and will not walk about naked, exposed to disgrace.”
What happens to those believers who are not ready, not prepared, not fit, not holy, and not chaste? What happens to them? Are they allowed into the Marriage festivities?
