find to be as good as settled.

The unhappy prodigal is in no condition to resist farther.
Chaplain Muller had introduced himself with Katte's dying
admonition to the Crown-Prince to repent and submit.
Chaplain Muller, with his wholesome cooling-powders, with his
ghostly counsels, and considerations of temporal and eternal
nature,--we saw how he prospered almost beyond hope. Even on
Predestination, and the real nature of Election by Free Grace, all
is coming right, or come, reports Muller. The Chaplain's Reports,

so eager to have error and darkness purged away. Believes himself,
as I believe him, ready to undertake that Oath; desires, however,
to see it first, that he may maturely study every clause of it.--
Say you verily so? answers Majesty. And MAY my ursine heart flow
out again, and blubber gratefully over a sinner saved, a poor Son
