Paul is of that view.
Philippians 3:11
Philippians 3:12
Philippians 3:13
Philippians 3:14
The key to understanding this passage is, I think, in the words, being made conformable to His death. He's telling us, he's not there yet. And a few verses later, he says,
Philippians 3:20-21 YLT
20) For our citizenship is in the heavens, whence also a Saviour we await—the Lord Jesus Christ—
21) who shall transform the body of our humiliation to its becoming conformed to the body of his glory, according to the working of his power, even to subject to himself the all things.
He doesn't seem to show any hesitancy there.
Philippians 1:3-7 YLT
3) I give thanks to my God upon all the remembrance of you,
4) always, in every supplication of mine for you all, with joy making the supplication,
5) for your contribution to the good news from the first day till now,
6) having been confident of this very thing, that He who did begin in you a good work, will perform it till a day of Jesus Christ,
7) according as it is righteous for me to think this in behalf of you all, because of my having you in the heart, both in my bonds, and in the defence and confirmation of the good news, all of you being fellow-partakers with me of grace.
Is his confidence for them misplaced?
Philippians 1:21-23 YLT
21) for to me to live is Christ, and to die gain.
22) And if to live in the flesh is to me a fruit of work, then what shall I choose? I know not;
23) for I am pressed by the two, having the desire to depart, and to be with Christ, for it is far better,
And again, no lack in confidence here.
Philippians 4:21-22 YLT
21) Salute ye every saint in Christ Jesus; there salute you the brethren with me;
22) there salute you all the saints, and specially those of Caesar's house;
The Spirit testifies with our spirit that we are the children of God. Do you have that testimony?
Much love!
