Philippians 3:15-21 KJV
15) Let us therefore, as many as be perfect, be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you.
16) Nevertheless, whereto we have already attained, let us walk by the same rule, let us mind the same thing.
17) Brethren, be followers together of me, and mark them which walk so as ye have us for an ensample.
18) (For many walk, of whom I have told you often, and now tell you even weeping, that they are the enemies of the cross of Christ:
19) Whose end is destruction, whose God is their belly, and whose glory is in their shame, who mind earthly things.)
20) For our conversation (Greek "citizenship") is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ:
21) 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.
So that "lower walk" is a fleshy walk, and the "higher walk" is the spiritual walk. But not that there is a Christian walk that is "fleshy", and an higher Christian walk that is "spiritual".
The Christian who walking in a fleshy walk needs to be transformed by the renewing of the mind, not by being "taken up" into that spiritual walk.
We are all called to walk in the Spirit, and in faith we do that. Some here are claiming that we are not able to, unless God gives us something extra, but what God says is, "If we live in the Spirit, let us also walk in the Spirit."
We aren't lacking the power to do so, the Spirit lives in us. It's a question of faith.
Much love!
