Eternal Life.

Living Through the Spirit.

"For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live." (Rom 8:13).

The life of the body is sustained by it's spirit. Pro 18:14 says that "The spirit of a man will sustain his infirmity; but a wounded spirit who can bear?"  Without the spirit, the body dies. And without the spirit, you can't see God, and whenever the spirit permanently leaves the body, the body die's. [Note that without a body you can't live on the Earth. You need a body to live this kind of life on Earth.] 

Jesus Christ died and rose again through the Holy Spirit of God in His Body. You can kill or destroy His Body billion times, but you can't destroy Him, because He will keep coming back to life! "Jesus answered and said unto them, Destroy this temple, and in three days I will raise it up." Jesus was pointing to Himself/ His Body when He said this, for His Body was the temple (of the Spirit) of God. So therefore, "Destroy this body and in three days I will raise it up" is what the Spirit is saying through Jesus here in John 2:19.  This is true because of the Holy Spirit indwelling the Body of Jesus, and also true for every believer and the Church in Christ. The Body/Church and our individual bodies is sustained by the Spirit of Christ.

The deeds of the body - what are these deeds? 

They are the (natural) laws working on the body. Since the fall, man's body has been lacking the required "Nutrients/Spirit" to sustain itself forever, because there is no more access to the fruit of the Tree of life. But we thank God for Jesus, whose Death and Resurrection has granted us the access to the Tree of life Himself, that is, Christ! We can now once again through Jesus Christ keep eating of the fruit of life and live forever more. [Note that if the body should die before its appointed time, it CAN be resurrected! Anything that causes untimely death is crushed by the Spirit (i.e, the Power of Resurrection) that is in us].

I Am Not Ashamed.

Knowing this that it is the very reason why John 3:16 "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life." is ever loaded with This eternal power of God..."For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth..." (Rom 1:16). Are you still ashamed?
