Part of the Mystical Body: by CS Lewis

Matthew 16:17-19 And Jesus answered him, “Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven.  And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it.

The Church will outlive the universe; in it the individual person will outlive the universe. Everything that is joined to the immortal head will share His immortality. We hear little of this from the Christian pulpit today. .... If we do not believe it, let us be honest and relegate the Christian faith to museums. If we do, let us give up the pretense that it makes no difference. For this is the real answer to every excessive claim made by the collective. It is mortal; we shall live forever. There will come a time when every culture, every institution, every nation, the human race, all biological life is extinct and every one of us is still alive. Immortality is promised to us, not to these generalities. It was not for societies or states that Christ died, but for men. In that sense Christianity must seem to secular collectivists to involve an almost frantic assertion of individuality. But then it is not the individual as such who will share Christ's victory over death. We shall share the victory by being in the Victor. A rejection, or in Scripture's strong language, a crucifixion of the natural self is the passport to everlasting life. Nothing that has not died will be resurrected. .... There lies the maddening ambiguity of our faith as it must appear to outsiders. It sets its face relentlessly against our natural individualism; on the other hand, it gives back to those who abandon individualism an eternal possession of their own personal being, even of their bodies. As mere biological entities, each with its separate will to live and to expand, we are apparently of no account; we are cross-fodder. But as organs in the Body of Christ, as stones and pillars in the temple, we are assured of our eternal self-identity and shall live to remember the galaxies as an old tale.
