I've never read the Epistle of Barnabas. Do the words in parentheses and brackets belong to the author or you?@Caroljeen
Here is the same thing put into other words by a first century Christian. He covers a lot of ground rapidly so you may have to read it a few times. Notice though that he allegorizes Joshua, son of Nun, and calls him “Jesus.” Then he proceeds to associate him with the “last Adam” being refashioned in Gen 1 by the Holy Spirit. Subsequently, he asserts that we are that “Adam“ because of “Joshua” leading us by the Spirit. If you read what I wrote above and compare it to this first century Christian you should see a parallel in perspective about the real Joshua (aka Jesus) being allegorically perceived as a moral consciousness from Hebrew scripture written on our heart or will.
(Epistle of Barnabas)
And Moses also says to them,
“Behold these things, saith the Lord God: Enter into the good land which the Lord swore [to give] to Abraham, and Isaac, and Jacob, and inherit ye it, a land flowing with milk and honey.”
What, then, says Knowledge (Greek: gnosis)?
Learn: “Trust,” she says, “in Him who is to be manifested to you in the flesh [in OUR flesh]—that is, Jesus (that is, Joshua, Son of Nun).” For man is earth in a suffering state, for the formation of Adam was from the face of the earth.
What, then, meaneth this: “INTO THE GOOD LAND, a land flowing with milk and honey?” …
Since, therefore, having renewed us by the remission of our sins, He hath MADE US after another pattern, [it is His purpose] that we should possess the soul of children, inasmuch as He has CREATED US ANEW by His Spirit.1509 For the Scripture says CONCERNING US, while He speaks to the Son,
“Let Us make man after Our image, and after Our likeness; and let them have dominion over the beasts of the earth, and the fowls of heaven, and the fishes of the sea.”
And the Lord said, on beholding the fair creature man, “Increase, and multiply, and replenish the earth.”These things [were spoken] to the Son. Again, I will show thee how, IN RESPECT TO US, He has accomplished a second fashioning in these last days. The Lord says, “Behold, I will make the last [Adam] like the first [Adam].”
In reference to this, then, the prophet proclaimed, “Enter ye into the land flowing with milk and honey, and have dominion over it.” Behold, therefore, WE have been refashioned, as again He says in another prophet,
“Behold, saith the Lord, I will take away from these, that is, from those whom the Spirit of the Lord foresaw, their stony hearts, and I will put hearts of flesh within them,”
because He was to be manifested in [our] flesh, and to sojourn among us. For, my brethren, the habitation of OUR HEART is a holy temple to the Lord.”
IOW, Joshua, Son of Nun, according to the type, is to be manifest in our flesh, written on our hearts, as a moral consciousness, leading us to the promised land, —leading us to “the good land.” And Our fleshy body, to include the material universe, is the “Temple” that currently houses the Joshua, son of Nun, according to the types.
What does Joshua the son of Nun have to do with Christ in us?
