Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; nor does corruption inherit incorruption. (1 Corinthians 15:50, NKJV)
Even though Jesus taught plainly that His kingdom “is not of this world” in John 18:36, many souls continue to believe His kingdom will be established as a future world government, with Jesus ensconced on His throne in Jerusalem. However, Jesus said His kingdom would come into existence “with power” during the lifetime of those who heard Him teach (Mk. 9:1). His kingdom was established through the powerful events recorded in Acts 2. His kingdom is His church (Dan. 2:44; Matt. 16:18-19). When Jesus returns on resurrection day, He will deliver the kingdom to God the Father, not set it up on the earth (1 Cor. 15:23-26). At that time, with resurrected, immortal bodies, we will enter the heavenly kingdom (2 Tim. 4:18). Our mortal, corruptible bodies will not inherit heaven. The kingdom of God is incorruptible and not of this world. Even so, only with resurrected, immortal bodies will God’s people pass into eternal life (1 Cor. 15:52-56). “Thanks be to God, who gives us the victory through our Lord Jesus Christ” (1 Cor. 15:57).
