And the Saviour must achieve a flawless perfection of character wholly without spot or blemish, which will permit Him to stand as a substitute for sinners whose character is totally unacceptable in the sight of God. Substitutionary sacrifice is at the root of this whole redemptive process. Only so can the tragedy of Eden be undone. A new history must begin with a new Head of a new race. Man is not, like the angels, a spiritual being only.
Man is a different order of being.
In the world to come, the resurrection of the body is therefore as essential to his wholeness as the continuance of his spirit is. Scripture is quite clear on this point. The quality and nature of his human existence will thus be re-established in the presence of God throughout eternity, and therefore man will have potential that the angels can never have. So the Saviour must be made flesh in order to become a substitute for the whole man. It is revealed that before embodiment He was Himself God the Creator, the Jehovah of the Old Testament.
