“…having escaped from the corruption that is in the world because of sinful desire.”
– 2 Peter 1:4
As a result of sin and the fall, man no longer lives the life that he have been living before; he has become alienated from God and the godly way of life, and the world in which he lives is likewise in a state of corruption. In other words, the world in which we live is a world that is inimical to our best and truest and highest interests; the world is for ever trying to come between us and God. If we listen to the world, as we all do by nature, it makes us not only think less and less of God, but even makes us feel that God is against us. It may even create an enmity against God, and a hatred of God within us. It gives us a positive liking and longing for the things that are hurtful to us, the things that debase us, the things that lower us, the things that drag us further and further away from God. Such is the corruption that is in the world through lust. The characteristic of man’s natural life is that its is a life lived according to desire. Man by nature does not ask, ‘Is it good, is this god-like, is this pure, is this clean, is this elevating, is this spiritual?’ He asks, ‘Do I like it?’ He is governed by his desires, by that which pleases him, and by that which panders to his lower nature. That is what Peter means by corruption – it is the corruption that results from lust or inordinate desire.
