“But even as hope seemed to die, it was turned to new strength.  …And he felt through all his limbs a thrill, as if he was turning into some creature of stone and steel that neither despair nor weariness nor endless barren miles could subdue.”                                                                                            J.R.R. Tolkien, The Return of the King (The Lord of the Rings #3)

Gather up oh my soul.  You are strengthened by the Holy Spirit to walk these miles.  When at the end, not another step is required, you will trade your rebar limbs for fresh ones, trained ones, everlasting ones, redeemed ones.

Until then, feel a thrill.
