Ever wondered how to remain pure in such an impure world?
1 Thessalonians 5:22
Abstain from all appearance of evil.
The highway of the upright is to depart from evil: he that keepeth his way preserveth his soul.
Both scriptures imply that once we recognize evil we should turn away from it. That once we turn away from it our judgment (discernment) should be well developed in the capacity to become aware of similar situations or circumstances, And once we are able to observe such situations or circumstances we should not respond nor chase after evil since that will only deem itself a reflection of our own evil. Stay pure!
