John 1:1-3 – In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made.
Thou hast a few names even in Sardis which have not defiled their garments; and they shall walk with me in white: for they are worthy. – Rev 3:4
We may understand this to refer to justification. “They shall walk with Me in white”; that is, they shall enjoy a constant sense of their own justification by faith; they shall understand that the righteousness of Christ is imputed to them, that they have all been washed and made whiter than the newly-fallen snow.
Again, it refers to joy and gladness—for white robes were holiday dress among the Jews. They who have not defiled their garments shall have their faces always bright; they shall understand what Solomon meant when he said “Go your way, eat your bread with joy, and drink your wine with a merry heart. Let your garments be always white, for God has accepted your works.” He who is accepted of God shall wear white garments of joy and gladness, while he walks in sweet communion with the Lord Jesus.
Whence so many doubts, so much misery, and mourning? It is because so many believers defile their garments with sin and error, and hence they lose the joy of their salvation, and the comfortable fellowship of the Lord Jesus—they do not here below walk in white.
The promise also refers to walking in white in heaven, before the throne of God. Those who have not defiled their garments here on earth—shall most certainly walk in white up yonder, where the white-robed hosts sing perpetual hallelujahs to the Most High. They shall possess inconceivable joys, happiness beyond all dreams, bliss beyond imagination, and blessedness which even the stretch of desire has not reached.
The “undefiled” shall have all this—not of merit, nor of works—but of grace. They shall walk with Christ in white, for He has made them “worthy.” In His sweet company they shall drink of the living fountains of waters!
