Whatever man uses without the fear of God, whatever he applies to the mere gratifying of his flesh, cannot fail to operate as a poison to the soul, however pleasant and salutary it may appear to be to the body.
Yet, so far from laboring to know the forbidden tree of worldly pleasures and its various fruits, man gives himself up to a careless and thoughtless state of life, and yields to the lust of the flesh, not considering that this lust is really the forbidden tree.
In short, all things that please the natural man in this world, are, to a true Christian, only so many crosses and temptations, allurements of sin and snares of death, that continually exercise his virtue.
This truth is a remedy against spiritual pride, namely, that none should account himself better before God than others, though perhaps adorned with greater gifts, and endowments.
