The deadliest enemy of holiness!

(Jared Waterbury, "Who are the Happy?")

How can a Christian expect to be happy, if he takes to his bosom the deadliest enemy of holiness--the world?

How can he expect that his soul will be filled with heavenly joys, when he is filling it with the groveling pleasures of this world?

"You adulterous people, don't you know that friendship with the world is hatred toward God? Anyone who chooses to be a friend of the world becomes an enemy of God!" James 4:4
