In Matthew 17, we read how Jesus took 3 of His disciples up a high mountain where He met with Moses and Elijah. Jesus “was transfigured before them. His face shone like the sun, and His clothes became as white as the light” (Matt 17:2; NKJV); see also Mark 9:3; Luke 9:29). The Greek word for transfigured is “metamorphoo” and can also be translated as changed or transformed.
In 2 Corinthians 3:18 (NKJV) the same Greek word is used, “But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord.” As Christians, with our spiritual eyes opened we can see the glory of Jesus in the word. The Holy Spirit will give us insight into who Jesus is, what He taught, how He opened the way to salvation and all He has for us. Faith in this revelation releases the Holy Spirit to transform us to be more and more like Jesus. We will come to be “conformed to the image of His Son” (Rom 8:29; NKJV), our minds will be renewed (Rom 12:2), we will receive His life in our mortal bodies (Rom 8:11) and we will walk just like Jesus walked (1 John 2:6).
I haven’t yet seen another person shine like Jesus did on that mountain, however, when Jesus returns, we are promised that “we shall be like Him” (1 John 3:2b; NKJV) and “you also will appear with Him in glory” (Col 3:4; NKJV). Hallelujah! Amen!
