What Greater Deception?

For my people is foolish, they have not known me; they are sottish children, and they have none understanding: they are wise to do evil, but to do good they have no knowledge. Jeremiah 4:22

"What greater deception can come upon human minds than a confidence that they are all right when they are all wrong! The message of the True Witness finds the people of God in a sad deception, yet honest in that deception. The unsanctified heart is 'deceitful above all things, and desperately wicked'......many are flattering themselves that they are good Christians, who have not a ray of light from Jesus. They have not a living experience for themselves." Testimonies for the Church vol.3, p.252,253
