Final glory that awaits us
From Gordon Fee’s commentary on Philippians, summarizing what Paul is saying in Philippians 3 and 3:20-21 in particular.
“But our citizenship is in heaven, and from it we await a Savior, the Lord Jesus Christ, who will transform our lowly body to be like his glorious body, by the power that enables him even to subject all things to himself.”
“This passage reminds us that, despite appearances often to the contrary, God is in control, that our salvation is not just for today but forever, that Christ is coming again, and that at his coming we inherit final glory that belongs to Christ alone–and to those who are his It means the final subjugation of all the “powers” to him as well, especially those responsible for the present affliction of God’s people. With Paul we would do well not merely to “await” the end, but eagerly to press on toward the goal, since the final prize is but the consummation of what God has already accomplished through the death and resurrection of our Savior, Jesus Christ the Lord.”
