I ought to be careful with what I hear or read. Too many people claim to know much more than they do - frequently out of ignorance while others do so intentionally. At the same time, I ought to recognise also that I know and understand only a thin slice, entrusting the Holy Spirit to guide me wade through the rest.

".. Test all things carefully [so you can recognise what is good]. Hold firmly to that which is good." (1 Thessalonians 5.21 AMP)
