For all that is in the world, the lust of the flesh, the lust of the eyes, and the pride of life, isn't the Father's, but is the world's.

 Then comes John's second warning. The man who attaches himself to the world's aims and the world's ways is giving his life to things which literally have no future. All these things are passing away and none has any permanency. But the man who has taken God as the centre of his life has given himself to the things which last for ever. The man of the world is doomed to disappointment; the man of God is certain of lasting joy.
