Some of God's righteous ones, alive by faith, will shrink back and be destroyed.
Hebrews 10
36For you have need of endurance, so that when you have done the will of God you may receive what is promised.
37For,
“Yet a little while,
and the coming one will come and will not delay;
38but my righteous one shall live by faith,
and if he shrinks back,
my soul has no pleasure in him.”
39But
we are not of those who shrink back and are destroyed, but of those who have faith and preserve their souls.
v36You have need of endurance, but some of v38God's righteous ones who live by faith do not endure, so God has no pleasure in them and so v39He destroys them.
