Even if we walk in and follow after the spirit, we still deal with the flesh. Paul said we are not yet perfect, he follows after, he said. I see it this way- Paul talks to us both spiritually and he talks about the flesh too because we are still living in the flesh, paul doesn't throw out all fleshy commands because we still live in a world of flesh. Paul said we should mind the same thing, this means that we are all equal, there is no higher plain of understanding which puts one person above another, there is just faith, love and hope, and there is brotherhood, and the greatest in the kingdom is the servant, not the scholar, and the greatest thing is love, not scholarship. We are dead and our life is hidden in Christ, in heaven. We are not yet perfected, not yet. It does not yet appear what we will be. Isn't this what scriptures say?
Philippians 3:12 It is not as though I had already attained it, nor were already perfect; but I follow after, that I may apprehend that for which Christ Jesus also apprehended me.
1 John 3:2 Beloved, now we are children of God; and it has not yet been revealed what we shall be, but we know that when He is revealed, we shall be like Him, for we shall see Him as He is.
1 Co 13:11 When I was a child, I spoke as a child, I understood as a child, I thought as a child; but when I became a man, I put away childish things. 12 For now we see in a mirror, dimly, but then face to face. Now I know in part, but then I shall know just as I also am known. 13 And now abide faith, hope, love, these three; but the greatest of these is love.
Colossians 3 If then you were raised with Christ, seek those things which are above, where Christ is, sitting at the right hand of God. 2 Set your mind on things above, not on things on the earth. 3 For you died, and your life is hidden with Christ in God. 4 When Christ who is our life appears, then you also will appear with Him in glory.
Colossians 3:5 Therefore put to death your members which are on the earth: fornication, uncleanness, passion, evil desire, and covetousness, which is idolatry. 6 Because of these things the wrath of God is coming upon the sons of disobedience, 7 in which you yourselves once walked when you lived in them.
8 But now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth. 9 Do not lie to one another, since you have put off the old man with his deeds, 10 and have put on the new man who is renewed in knowledge according to the image of Him who created him, 11 where there is neither Greek nor Jew, circumcised nor uncircumcised, barbarian, Scythian, slave nor free, but Christ is all and in all.
Character of the New Man
12 Therefore, as the elect of God, holy and beloved, put on tender mercies, kindness, humility, meekness, longsuffering; 13 bearing with one another, and forgiving one another, if anyone has a complaint against another; even as Christ forgave you, so you also must do. 14 But above all these things put on love, which is the bond of perfection. 15 And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful. 16 Let the word of Christ dwell in you richly in all wisdom, teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord. 17 And whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him.
