The “kingdom of religion” can be roughly divided into two halves:
a) Those with a guilty conscience.
b) Those with a seared conscience.
With the former, everything they say, do or think is the outworking or product of a guilty conscience. Religion is the Panadol for their guilt, they are on a treadmill chasing a carrot, and a clear conscience is always just out of reach.
With the latter, they have dealt with their guilty conscience simply by denying it exists, burying their heads in the sand until Judgment Day. Everything about them is the product of a seared, or dead conscience. As Jude described, they turn the grace of God into a license to sin. Of course, they don’t say they have a license to sin, they simply deny their sin is sin, which is the same thing in the sight of God.
However, a pure, washed-in-the-precious-blood-of-Christ conscience is the only source of anything pure. All that is pure and real flows from a pure conscience.
