You have no reason to complain

(Thomas Boston, "Human Nature in its Fourfold State")

"Why does a living man complain?" Lamentations 3:39

You have no reason to complain, as long as you are
out of hell. Do you murmur, because you are under pain
and sickness? Nay, bless God, you are not there where
the worm never dies! Do you grudge, that you are not in
so good a condition in the world as some of your neighbors
are? Be thankful, rather, that you are not in the condition
of the damned! Is your money gone from you? Thank God
that the fire of His wrath has not consumed you! Kiss the
rod, O sinner! and acknowledge mercy!
