ISB ~ 1 Corinthians 15 v50

flesh and blood:A Semitic idiom for human beings, weak and subject to corruption (Sir 14:18; Mt 16:17). Paul is not denying that resurrected bodies will have flesh and blood; his point is that our physical bodies cannot enter God’s kingdom in their present state of weakness; they must be radically “changed” (1 Cor 15:51).
