A good article enlightening a truth many Christians fail to understand, particularly the very first sentence "The sign of Christ IN us is the manifestation of His nature THROUGH us". God created man "in his image and after his likeness" (Gen 1:26) so that on earth (in the physical) where he (God) cannot be seen, his nature (that which is in the spirit) will be displayed by his sons in the physical for all of creation to see (Romans 8:19). We know the story of how Adam was tricked in the Garden of Eden of this ability. But alas, many years later, the Son of God came into the physical (reincarnated); his coming was not only to save us from sin but to show us not to fall into the same mistake Adam fell into. Jesus life on earth demonstrated to us that a physical body, just like the one you and I have has the ability to display the nature of God and function fully to the purpose it was intended on the drawing board in the mind of God (Eph 1:4, Jeremiah 1:5, Gen 1:26). If we want to overcome our misfortunes and problems and the world's we have to go back in time, find the purpose that God had for us (man) and strive to live the way we were hence designed.
