New Defender's Study Bible Notes
1:5 virtue. “Virtue” is not mere moral goodness, but spiritual valor, or strength of character.
1:7 brotherly kindness. “Brotherly kindness” (Greek philadelphia) is elsewhere translated “brotherly love.”
1:7 charity. “Charity” (Greek agape) is commonly rendered “love.” This type of love is thus distinct from brotherly love. It involves deep respect for a person, recognizing the value and interests of that person, and caring for him or her as a person of genuine worth.
1:8 barren. “Barren” means, literally “idle.” A fruitful and effective Christian life and work will be the natural product of true Christian character.
