What is the spirit of the anti-christ? It is the notion that man can work out his own problems and that we ourselves can usher peace into the world apart from divine intervention. It is a denial that we are broken and in need of a Savior. It is a display of pride that reflects a high regard for our own abilities to overcome the problems of this world through the unity of mankind rather than working within the unity of the Holy Trinity. It is a denial of sin, it's consequences and the day of judgement. Ultimately, it is a denial of the work of the Son of God to save mankind through the cross and His resurrection.
