Philippians 3:21

Textus Receptus:
ος μετασχηματισει το σωμα της ταπεινωσεως ημων εις το γενεσθαι αυτο συμμορφον τω σωματι της δοξης αυτου κατα την ενεργειαν του δυνασθαι αυτον και υποταξαι εαυτω τα παντα

King James:
Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.

Comments:
change: The word for change is very strong, as in "transform," and is from the compound of the prefix "meta" and the Greek word used about Jesus' "fashion as a man" in chapter 2:8.

vile: This word is translated "humble" or "lowly" in other places and is used about Jesus as a verb in chapter 2:8.

fashioned like: This word is the Greek prefix for "together" and the word used about Jesus being in the "form" of God in chapter 2:6.

glorious: It is only after the humiliating crucifixion of Christ that His exaltation becomes apparent in chapter 2:9-11. Paul's command for believers to avoid "vainglory" in chapter 2:3 (a compound of this word) is followed by his command for them to have the mind of Christ who then humbles Himself to the cross before He is exalted by His Father. Paul is telling believers they must make the same journey, as he does in 2 Timothy 2:11-12 as well.

working...subdue all things: Paul is specific here about the confidence he exhibits in chapter 1:6. Jesus will finish His work in believers because He has led the way with His own sacrifice and example and because He will return to receive His rightful inheritance, including their full submission to Him.

Expanded Paraphrase:
And when He does fulfill our expectation--when He does come back for us--He will transform the humbled body we endure in this world so that it becomes like His perfected and exalted body. Just as His death led to His glory, He will accomplish the work of transforming our sacrifice and loss into reward. But for us, the reward is that we will finally be fully submitted to Him.

Philippians 2:3-11 Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves. 4 Look not every man on his own things, but every man also on the things of others. 5 Let this mind be in you, which was also in Christ Jesus: 6 Who, being in the form of God, thought it not robbery to be equal with God: 7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: 8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross. 9 Wherefore God also hath highly exalted him, and given him a name which is above every name: 10 That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; 11 And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.

2 Timothy 2:11-12 It is a faithful saying: For if we be dead with him, we shall also live with him: 12 If we suffer, we shall also reign with him: if we deny him, he also will deny us:
