No star is ever lost we once have seen,We always may be what we might have beenSince Good, though only thought,Has life and breath -God's life - can always be redeemed from death.And evil in its nature is decay,And any hour may blot it all away.The hope that lost in some far distance seems,May be the truer life, and this the dream.
