Lets look at this....
'"walking.....................IN...........THE Spirit."""
So, whose Spirit?
Yours?
It can't be yours, as your Spirit is already always ON. Its ALIVE, and made so by God.
See, you dont learn to walk in THAT, as that is already constantly in process = born again.
So, that means, you are to walk in someone else's.
How do you walk there?
You walk there the same way you are : "seated in Heavenly places in Christ".
You walk there the same way you the born again have become...."As Jesus IS< so are the born again IN THIS WORLD".
You walk there the exact same way you are in the world but not OF It, because you have been "translated From Darkness.....TO LIGHT".
So...
This is why the verse tells you to walk in THE Spirit.
See, The verse is talking to you, spiritually, and not just as words on a page.
And remember, ....when you are learning how to see the light in the word, and not just the words on the page, there are keys, to notice.
And one of them is to notice = "THE". As often the NT will be talking about something SPECIFIC and not in the general sense, and so, it will say....."THE"....>"THE"......"THE".........as in Jesus is THE Way, and not just a way. And Christ hung on THE Cross, and not just a cross.
See that?
Notice the "THE's.
Now, when you are told to walk in THE Spirit, then that is a Specific direction and not just a random or general idea.
And the "walking" in this verse, is not you trying to be good, or you trying to live right, or you trying to present your body as a living sacrifice, as all that is just generic discipleship.
So, what is "THE Spirit"?.... = Its Jesus's MIND of Faith and Belief.
Its this....>"the MIND of Christ".
Its this, > "God's Perspective, regarding all things".
And for you to get THERE, within your Spirituality, you have to "Put on the new man", and "renew your mind".
And that means,
