Because of the wisdom contained within, we should trust the Bible.
Nowhere else can you find wise words to cover every aspect of life's challenges that you might find. Nowhere else is there a complete system to explain everything that you might need to know about anything (and that actually makes sense).
Unfortunately, not everyone has eyes to see or ears to hear. Fools despise wisdom. How do you respond to the pearls below?
Pearls from the Bible:
Blessed is the man (and woman) who takes no advice from wicked people (Psalm 1:1)
Men can "sharpen" each other (proverbs 27:17) [two of similar minds/character reinforcing]
It is nothing special to love those who love you back. Even a bad person does that. Instead, love those who hate you (Matthew 5:43-46)
Man has an innate sense of eternity and morality (Ecclesiastes 3:11, Romans 2:15)
