(6) A right heart is a heart that FEELS CONFLICT within it.
“For the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary to one another, so that you do not do the things that you wish.” (Galatians 5:17)
It finds within itself two opposing principles contending for the mastery—the flesh lusting against the spirit, and the spirit against the flesh.
It knows by experience what Paul means when he says,
“I see a law in my members warring against the law of my mind” (Romans 7:23).
The wrong heart knows nothing of this strife. The strong man keeps the wrong heart as their palace, and their goods are at peace (Luke 11:21).
But when the rightful King takes possession of the heart, a struggle begins which never ends until death.
The right heart may be known by its warfare, quite as much as by its peace.
