Wisdom begins with correction. Errors must be exposed. Mistakes must be admitted. Think back over your life. Think of the person who taught you the most. He was probably the one who corrected you the most.
Hell is full of people who rejected correction. Heaven is full of people who accepted it.
“For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth.”
“Now no chastening for the present seemeth to be joyous, but grievous; nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby.”
