The most important determining factor in a person’s life is their character. Your character includes all aspects of your inner being— your social awareness, your intelligence quotient (IQ), your emotional quotient (EQ), and your spiritual maturity. If someone is deficient in one of these areas it will limit their ability to be the person that God wants them to be! So Paul encourages Timothy to reject his immature tendencies of adolescents and diligently pursue the heart of God.
