You are using a few scriptures of what Paul has said and not what Christ has said. Just because it came out of the Bible does not mean you should ignore who is saying what. Christ tells us that as he is in heaven so are we in this world. Is there sin in heaven? Is Christ struggling in heaven of any of the things you mentioned.

Why does Christ also tells us to be holy just as he is holy if we are not able to? You have the right book but the wrong writers. Don't put so much weight on what the Disciples teach and preach because they even seem to forget some of the things Christ taught them. You also make it seem as if it's recorded in the bible it doesn't matter who says what?

My God Dad taught me that you should always know who said what in the Bible so that there are no confusion. I agree with him. Also, I would rather listen to the Word of God (JESUS CHRIST) than just those who testify about him.
