And having done all, to stand (Eph 6:13)

Luther, to Erasmus, in Bondage of the Will:

For even I, by the grace of God, am not such a fool or so mad as to have been willing to maintain and defend this cause for so long, with so much zeal and constancy (which you call obstinacy) amid so many dangers to life, so much hatred, so many treacheries, in short, amid the fury of men and demons, simply for the sake of money (which I neither possess nor desire), or popularity (which I could not obtain if I wished, in a world so incensed against me), or physical safety (of which I cannot for a moment be certain) . . . .

When nothing else can be done, we prefer to be battered by temporal tumult, rejoicing in the grace of God, for the sake of the Word of God, which must be asserted with an invincible and incorruptible mind, rather than to be shattered by eternal tumult under the wrath of God, with intolerable torment.

--LW, 33:51
