Man-centered, works-based, freewill religion — call it by any name you will — is the single greatest evil in this world. . . and is the greatest cause of evil in this world.
The good works of religion without Christ are the most abominable evils imaginable. . . Man-centered, freewill works-religion robs God of His glory, tramples underfoot the blood of Jesus Christ, does despite to the Spirit Of Grace, and gradually abases society to its lowest, most contemptible state. . . ‘Evil workers,’ as Paul describes them in this context, are Arminians — freewillers, legalists — people who teach that God’s salvation depends on, or is in some way determined by, man: ‘evil workers.’
Ephesians 2:8-9King James Version
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9 Not of works, lest any man should boast.
