Jesus says, "Watch! Beware!"

speaking of your unique temptation times, areas, and situations.... Owen writes:
Unless he know it, unless his eyes be always on it,
unless he observes its actings, motions, advantages, it will continually be
entangling and ensnaring of him.

Labor to know your own frame and temper;
what spirit you are of;
what associates in your heart Satan has;
where corruption is strong,
where grace is weak;
what stronghold lust has in your natural constitution,
and the like.
