“Jesus Christ the same yesterday, and today, and forever” (Hebrews 13:8) says: “God is a Spirit: and they that worship him must worship him in spirit and in truth” (John 4:23–24).
Paul, the Apostle to the Gentiles said: “So then they that are in the flesh cannot please God” (Romans 8:8).
To get to the Paradise of God to be with God forever, our human body must become a quickening Spirit. Only Jesus Christ has been given the power to quicken our mortal bodies (John 3:16-18, 14:6).
The Apostle Paul also 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).
“For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit. For to be carnally minded is death; but to be spiritually minded is life and peace. Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be. So then they that are in the flesh cannot please God” (Romans 8:5-8).
“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).
