The context is not the state of the believer. But is whether where there will be the word of God prophesies, they will fail and if prophecy by tongues they will cease and therefore any new knowledge it shall vanish.
Look at these verses I Corinthians 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. (NKJV)
This is about Paul personally. Before the perfect comes, he was like a child in his thinking and understanding. After the perfect comes, he wil be like a man in his knowledge and understanding. Notice 'we see in a mirror'. When the prefect comes, "I shall know just as I also am known.'
Can you really say that your speech, knowledge, and understanding, as a man who has the completed Bible is like an adult's in comparison to the ones who wrote the scriptures you read? By reading their childish understanding, you become a man in your understanding? Isn't that a foolish way of reading this passage? Paul is not focusing on the Bible hear, calling it childish understanding. Rather, he is speaking of his own understanding. And when the rapture/resurrection event occurs, we will be transformed. We shall be like Him, for we shall see Him as He is. This will change the way we speak, think, and understand.
That fits with what is described in the passage. It is also consistent with the fact that Paul leads up to a discussion of the resurrection and the transformation of them that shall 'not all sleep' a couple of chapters later, and I Corinthians 1:7 'So that ye come behind in no spiritual gift, waiting for the coming of our Lord Jesus Christ.'
For we know the word of God, prophecy in part but when the last verse (Revelation 22:21) comes we heed the warning not to add or subtract from the book of prophecy. The bible.
Many pages back, you acknowledged that the prophecies from God the Old Testament does not include in the Bible-- prophecies of Samuel between that one as a child and the one when he was an old man, Saul's prophecy, the prophecies of the prophets he met from Shiloh, prophecies of the prophets who were killed in the time of Jezebel, etc-- did not have to be added to the Bible.
You acknowledged, therefore, that a prophecy could be from God without it belong in the Bible. You acknowledged that these were real prophecies that were not in the Bible.
But yet you continue with this line of argument that if someone prophecies something that is not in scripture, he is adding to scripture.
That law book the bible will remain until the new heavens and earth appear and we receive our promise the new incorruptible bodies. The bible would have served it purpose.
Do you think of the Bible as 'that which is in part' which 'shall be done away', then? We should expect prophecy and knowledge to continue until we are resurrected, then? Are you changing your stance on the issue as you write?
