John 17:5 “And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was.”
The celestial glory that Jesus had from the beginning was temporarily hidden (veiled), during His earthly life. At the ascension of Christ, Jesus was both glorified and transfigured.
It is interesting to contrast the post-resurrection appearances of Christ with the post-ascension revelations. In the former, Christ often concealed His glory to the point that He was not recognized, such as by the disciples at Emmaus (Luke 24:16; 31), or by Mary Magdalene who thought He was the gardener (20:14).
The post-ascension revelations involve His radiant appearance. The difference between John’s meeting with Christ (in John 21), and in (Revelation 1), was that of seeing the Resurrection body, not glorified, and of later seeing the transformed and celestial body glorified.
For the Creator of the world to be housed in a body of flesh, had to be a terrible come- down. This had all been planned from the beginning to restore fallen man to fellowship with the Father. The first flesh man (Adam), had failed. This is why it was necessary for Jesus to take on the form of flesh.
The second Adam (Jesus), would restore mankind to full fellowship with God.
1 Corinthians 15:22 “For as in Adam all die, even so in Christ shall all be made alive.”
1 Corinthians 15:45 “And so it is written. The first man Adam was made a living soul; the last Adam was made a quickening spirit.”
John 3:6 “That which is born of flesh is flesh: and that which is born of the Spirit is spirit.”
The glory of the Father is in the Son. The Son will return to His original glory in heaven, and we will join Him there.
Someday Christians will also be glorified together with Christ (Romans 8:17).
Verses 6-10 “thine they were”. This phrase sums up all of Jesus’ ministry, including the cross that was just hours away. Again, the Son emphasized that those who believed in Him were given by the Father. “They are thine” (verse 9), is a potent assertion that before conversion, they belonged to God (6:37).
That is true because of God’s election. They were chosen before the foundation of the world (Eph. 1:4), when their names were written in the Lamb’s book of life (Rev. 17:8 and Acts18:10), where God says He has many people inCorinth who belong to Him but are not yet saved.
Acts 18:10 – “For I am with thee, and no man shall set on thee to hurt thee: for I have much people in this city.”
Note: This is an opportune time as a teachable moment to show an example of the “predestination” of God’s elect. God had appointed many people in Corinth for salvation, who had not yet heard the gospel (13:48, Romans 10:13-15). The effect of Paul’s preaching would be to bring the elect to faith (Titus 1:1).
