The Ruin of Satan and the Glory of Christ

Hereon depends the ruin of Satan and his kingdom. His sin, so far as we can conceive, consisted of two parts:

1. 1.His pride against the person of the Son of God, by whom he was created. “For by him were all things created that are” (or were when first created) “in heaven, whether they be thrones, or dominions, or principalities, or power,” Col. 1.16. Against him he lifted up himself; – which was the beginning of his transgression.
2. Envy against mankind, made in the image of God, of the Son of God the first born. This completed his sin; nothing was now left whereon to act his pride and malice.

Unto his eternal confusion and ruin, God, in infinite wisdom, unites both the natures he had sinned against in the one person of the Son; who was the first object of his pride and malice. Hereby his destruction is attended with everlasting shame in the discovery of his folly, wherein he would have contended with infinite wisdom, as well as misery, by the powers of the two natures united in one person.
