I was just going to let this die, but will go ahead and do what I did not want to, even though I know what is going to happen. So, here goes...
Peter said 'Become holy in all your conduct, because it has been written, 'Be holy, for I am holy.'
Here is a classic example of the difference between the idea of becoming, and of being. In the example I gave in the previous post, only a male can be told to 'be a man', not a woman. The reason is simple enough. A man is a man, while a woman is not. One can never 'be' what they are not.
Christianity often speaks out of lack, rather than out of reality. Those who do this would interpret Peter's words to mean:
'Become holy in all your conduct, because it has been written, 'Become holy, for I am holy.'
It would be foolish for Peter to tell them to 'become holy'. Why? Because they already WERE holy.
HOWEVER...
Just because one is holy doesn't mean we will always act like it. This was the case here. Peter was very careful in what he said. He did not say to 'become holy.' What he said was 'become holy IN ALL YOUR CONDUCT.'
And what is the basis upon which he could encourage them to become holy in all their conduct? THAT THEY WERE ALREADY HOLY! Remember, you cannot be what you are not already.
Peter spoke out of the reality of their being holy already, not out of lack, as though they were not holy and needed to work to become holy. No, he was merely encouraging them to act OUTWARDLY as they already were INWARDLY.
In the example I gave of the man, for me to encourage a man to 'be a man' implies that they are already a man, but are not acting like a man. I would be encouraging them to act like what they are.
Here is where it gets very exciting...
Adam and Eve were the first to, as husband and wife...'become one flesh.' This means they currently were not one flesh. They had not come together yet to make that happen. Now, once they have become one flesh, any further encouragements would be to 'be one flesh.'
To me, this sheds a whole new light on otherwise very familiar passages, but as Jesus words:
'...that they may be one, as we are one.'
I have always been taught to read this as becoming something that I was not currently. The idea presented is that man was not one with God, and Jesus came to make man one with God. But, what if man was always one with God, but that the reality of that was hidden from man by means of death and the experience of a separated mind from God, and that Jesus came, not to make us one with God, but to remove the barrier which prevented us from seeing the truth, which is we are one, and have always been one, with him? And I mean all mankind, not just us believers. We are simply the one who are having the blinders removed (so to speak).
Therefore, to 'be one', is to either see (or be seen) as one with God, and thus enabled to behave out of that reality.
