[1 John] 3:2 Shall be like him, like Christ, sons in freedom and glory (Cf. Jn 12:26; 8:18, 21, 29; Ph 3:21; Cl 3:4)
[1 John] 3:3 Hopes...purifies himself. This unbreakable connection between hope and purity of life, between the confidence in the returning Christ that looks to Him for everything and the resolute self-committal that devotes everything to Him, is the hallmark of all NT teaching on hope, from John the Baptist to John the prophet on Patmos.
