Jesus is Light unto humanity. Adam’s disobedience brought death upon mankind. Man died the day Adam disobeyed God’s commandment and ate of the tree which God commanded him not to eat. Although Adam lived physically but he was dead spiritually.
This spiritual death is the exit of man from the nature of the image and likeness of God into the nature of sin. Man died from divinity into carnality. Man became disconnected from God Who is Spirit. Man became a natural being that is limited to his senses. He cannot discern or comprehend the affairs of the Spirit because they are spiritually discerned. In other words it is a spiritual man that can understand the Spirit but a natural man is constraint to the affairs of the physical realm.
The fallen man or the natural man is a man living in darkness because he cannot see beyond his senses. His operations are limited to the physical realm.
The body without the spirit is dead. The natural man is an enemy of God. He is a hopeless being without God. He is under the operations of the powers of the kingdom of darkness.
Satan blindfolds the natural man so that he can not see beyond his senses. Satan takes advantage of the blindness of the fallen man to keep him under perpetual bondage. Satan takes advantage of the ignorance of man to influence his actions. The natural man does the things he doesn’t like but cannot do the things he likes. This is the wretchedness and hopelessness of living in darkness.
Jesus is the true Light that came from God. He is the express image of the Father. No one knows the Father except the Son.
Jesus came to show the Father to as many as will receive Him into their life. The life of Jesus in a man is light unto that man.
The Light shines where there is darkness and drives away the darkness. Darkness cannot withstand the presence of light.
Receiving the life of Jesus brings the man into Light. Man becomes aware of Whom the Father is, and becomes aware of whom the Father have made him, and also becomes aware of the things the Father have freely given to him.
This Light is knowledge. The Bible says that we shall know the truth, and the truth will make us free. This knowledge brings deliverance from the operations of the powers of the kingdom of darkness.
Jesus is the Light that deliver mankind from darkness. The Light shines in darkness and darkness cannot quench it.
