You believe as the Nicolaitans did?
The doctrine of the Nicolaitans appears to have been a form of antinomianism. (Antinomianism: A belief that is based upon a recognition of the mercy of God as the ground of salvation, but it makes the fatal mistake that man can freely partake in sin because the Law of God is no longer binding. It held the truth on the gratuitous reckoning of righteousness; but supposed that a mere intellectual “belief” in this truth had a saving power.
If so, you need to read Rev 2:12-17
I believe as St Augustine taught. Faith is a gift of strength from God. It is your tool to deal with difficult times, and like all strength it grows through use. It’s not a hot house flower that needs to be protected from the world, it protects you. Nothing about freely partaking in sin, faith gives you the strength to NOT partake in sin. It’s your shield.
