"As He prayed, the appearance of His face was altered, and His robe became white and glistening." (Luke 9:29)
Following the experience of Jesus as He prayed at the Mount of Transfiguration, there’re those who think they’d always have to go to that particular mountain to get transfigured. But no; it was just a mountain.
Evidently, Jesus was often transfigured as He prayed, but the account in Luke 9 was one occasion that the disciples had the opportunity to be present and see Him transfigured before them. God opened their eyes on that occasion to see what was happening with Jesus—the resplendent glory that effused from Him. If their eyes hadn’t been opened, they wouldn’t have seen the transfiguration. It was spiritual, for they saw Elijah and Moses as well, who disappeared as the vision faded.
Now, what happened to Jesus at the Mount of Transfiguration happens to us most of the time as we pray in the Holy Ghost; we’re transfigured; we literally glow from inside out. It’s something spiritual; that’s why those around you may not see or notice anything, except the Lord opens their eyes, like He did the disciples.
The glory of God is in your spirit; your spirit is glorified with Christ. That glory radiates from within and permeates everything around you when you pray, when you study, and when you meditate on God’s Word.
Remember the testimony of Stephen in Acts 6:15, when he was arrested and brought before the council. The Bible says his face looked to them like that of an angel. They didn’t always see Stephen’s face aglow like that every day, and everywhere he went. The people’s eyes were suddenly opened to see the glory on his face at that particular moment.
A similar occurrence took place when Jesus appeared to two of His disciples, after His resurrection. He walked with them a long distance, and even followed them home, yet they didn’t recognize Him. But as He partook of the Communion with them, their eyes were opened, and they recognized Him, but he promptly vanished from their sight (Luke 24:16-31).
Others may not see the glory all over you. Their eyes may not be opened to see it on your face, but one thing is sure: the glory of God is on you, and in your spirit! You’re constantly transfigured from glory to glory as you fellowship the Spirit; it’s one of the many glorious benefits of prayer.
I'm constantly transfigured, being filled with the Spirit. As I speak in tongues, there's an unleashing of the supernatural and all-round transformation in my spirit, soul, and body. My spirit gains the ascendancy and power over anything that's of the world, and I rise higher and higher like an edifice, in Jesus' Name. Amen.
