I have written to you, fathers, because you know him who is from the beginning. I have written to you, young men, because you are strong, and the word of God remains in you, and you have overcome the evil one.
      2. From the prohibition of worldly love or lust; it is not ordained of God: It is not of the Father, but is of the world,1 John 2:16; 1 John 2:16. This love or lust is not appointed of God (he calls us from it), but it intrudes itself from the world; the world is a usurper of our affection. Now here we have the due consideration and notion of the world, according to which it is to be crucified and renounced. The world, physically considered, is good, and is to be admired as the work of God and a glass in which his perfections shine; but it is to be considered in its relation to us now in our corrupted state, and as it works upon our weakness and instigates and inflames our vile affections. There is great affinity and alliance between this world and the flesh, and this world intrudes and encroaches upon the flesh, and thereby makes a party against God. The things of the world therefore are distinguished into three classes, according to the three predominant inclinations of depraved nature; as, (1.) There is the lust of the flesh. The flesh here, being distinguished from the eyes and the life, imports the body. The lust of the flesh is, subjectively, the humour and appetite of indulging fleshly pleasures; and, objectively, all those things that excite and inflame the pleasures of the flesh. This lust is usually called luxury. (2.) There is the lust of the eyes. The eyes are delighted with treasures; riches and rich possessions are craved by an extravagant eye; this is the lust of covetousness. 3. There is the pride of life. A vain mind craves all the grandeur, equipage, and pomp of a vain-glorious life; this is ambition, and thirst after honour and applause. This is, in part, the disease of the ear; it must be flattered with admiration and praise. The objects of these appetites must be abandoned and renounced; as they engage and engross the affection and desire, they are not of the Father, but of the world,1 John 2:16; 1 John 2:16. The Father disallows them, and the world should keep them to itself. The lust or appetite to these things must be mortified and subdued; and so the indulging of it is not appointed by the Father, but is insinuated by the ensnaring world.
