What is glorification according to the Bible?

from the old testament

• The Old Testament often depicts God’s faithful people being preserved, vindicated, or restored after trials, pointing to a future where His people are fully blessed and secure (Psalm 16:10–11; Daniel 12:2).
• God’s glory and the way His presence purifies and transforms those who approach Him hints at the ultimate sanctification of believers (Exodus 33:18–23; Isaiah 6:1–5).
• Some passages, especially in Daniel and the Psalms, anticipate the resurrection of the righteous to eternal life, showing God’s plan to give His people a perfected, eternal state (Daniel 12:2; Psalm 49:15).

from the new testament

• Glorification is the final stage of salvation, completing God’s saving work (Romans 8:30). While justification declares a believer righteous, glorification actually removes all remaining sin, fully transforming them into Christ’s likeness so they can dwell with God forever.
• Glorification happens for all believers at the same time: when Jesus returns. Paul wrote that “we shall all be changed, in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we shall be changed” (1 Corinthians 15:51–52). Elsewhere, Paul adds that “we await a Savior, the Lord Jesus Christ, who will transform our lowly body to be like his glorious body” (Philippians 3:20b–21a).
• Glorification is also the moment when believers are made fully righteous. Jude speaks of God presenting His people “blameless before the presence of his glory with great joy” (Jude 24–25).
• Revelation promises a future where “there will no longer be any curse” (Revelation 22:3).
• John adds in 1 John 3:2 that “when he appears we shall be like him, because we shall see him as he is.” These are all indicators that there is something special about seeing Jesus at His return that will be the catalyst for the believer’s transformation into his or her glorified self.
• While it’s clear believers will be glorified, the Bible is not clear what that means for our physical bodies. However, Jesus was the first to be resurrected in a glorified state, and His post-resurrection body offers some clues. He was recognizable to His followers (John 20:27), able to eat (Luke 24:42–43), and able to appear in a locked room (John 20:19). Therefore, it is likely that believers will also be recognizable with some continuity with life on earth now, yet with bodies somehow changed to be capable of eternal life with God.

implications for today

Glorification is the certain end for every believer. What a great hope to remember even as you struggle with sin in the present! You may wonder why your progress is so slow, but God has already declared the end of your story: He will finish His work, and you will one day be completely free from sin.

We do not understand what it will feel like to be entirely holy or to live in a body untouched by weakness. But that future is why Christians throughout the ages have longed for Christ’s return.

The next time you stumble, remember that glorification is not based on your strength. If you are a believer, God counts you as righteous even as you sin because Jesus has already paid for all of your sins. That doesn’t mean you should gladly continue to sin, but you should be grateful to remember that He will never leave you and will complete what He started in you.

Christ will return, and when He does, you will be what He has always intended you to be. Continue to press forward all the while looking for His return!
