And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever.
The world - with all who are of the world worldly.
Passeth away, х paragetai (G3855)] - 'is passing away' even now.
The lust thereof - in its threefold manifestation (1 John 2:16).
He that doeth the will of God - not his own fleshly will, or that of the world, but that of God (1 John 2:3-6), especially as to love.
Abideth forever - `even as God abideth forever' (with whom the godly is one, cf. Psalms 55:19): a true comment, which Cyprian and Lucifer added to the text without support of Greek manuscripts. In contrast to the three passing lusts of the world, the doer of God's will has three abiding goods, "riches, honour, and life" (Proverbs 22:4).
