I Corinthians 8:2

And if any man think that he knoweth any thing, he knoweth nothing yet as he ought to know (KJV)

Then: Those who know the truth, but lack love, know nothing because as Henry says, their pride rends their knowledge useless. Human knowledge is valuable only as it is edified by love. Paul wanted the Corinthians to understand the heart of serving Christ. His love for those he created is embedded within us, pushes out any demeaning ideas, attitudes and behaviors towards both fellow believers and non-believers. Rules must be known and followed, but compassion brings results. Keep the teaching, but leave off the final judgement.

Now: We need the same love - along with the same knowledge of his heart and teachings. Discovery, self-check, methods are difficult to come by and apply. Concentrating on Paul's teaching here and identifying twenty-first century gods, is necessary first step. .
