To get to Heaven to live with God and his only begotten Son human beings must be changed into a Quickening Spirit.
Jesus, the only begotten Son of God is the ONLY person that God has given power to change from the earthly to the heavenly (John 3:16-18, 5:21–22, 14:2–3).
“And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit” (1 Corinthians 15:45).
“And as we have borne the image of the earthy, we shall also bear the image of the heavenly” (1 Corinthians 15:47–49).
Jesus says: “It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life” (John 6:63).
“For as the Father rises up the dead, and quickeneth them; even so the Son quickeneth whom he will. For the Father judgeth no man, but hath committed all judgment unto the Son” (John 5:21–22).
The Apostle Paul also explained, said: “Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption” (1 Corinthians 15:50).
“But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness” (Romans 8:9-10).
“The Spirit itself beareth witness with our spirit, that we are the children of God: And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together” (Romans 8:16-17).
“Therefore, brethren, we are debtors, not to the flesh, to live after the flesh. 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” (Romans 8:12-13).
“Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting” (Galatians 6:7-8).
