New Defender's Study Bible Notes
3:3 purifieth himself. The hope of Christ’s second coming is not a dead hope, but a “lively hope” (I Peter 1:3); not a frightening prospect, but a “blessed hope” (Titus 2:13). It is a joyful hope (I Thessalonians 2:19), a comforting hope (I Thessalonians 4:13-18), a hope of glory (Colossians 1:27) and an anchoring hope (Hebrews 6:19). Finally, as this verse notes, it is a purifying hope, for it stimulates us to abide in Him.
