Yet another example is that of the tongue and the sense of taste. If you do not sell it to your Wise Creator, but employ it instead on behalf of the soul and for the sake of the stomach, it sinks and declines to the level of a gatekeeper at the stable of the stomach, a watchman at its factory. But if you sell it to the Generous Provider, the the sense of taste contained in the tongue will raise to the rank of a skilled overseer at the treasuries of Divine compassion, a grateful inspector in the kitchens of God's eternal power. Compare all other tools and limbs to these, and then you will understand that in truth the believer acquires a nature worthy of Paradise and the unbeliever a nature conforming to Hell. The reason for each of them attaining his respective value is that the believer, by virtue of his faith, uses the trust of his Creator on His behalf and within the limits traced out by Him, whereas the unbeliever betrays the trust and employs it for the sake of the concupiscent soul.
Man is helpless and exposed to numerous misfortunes.
He is indigent, and his needs are numerous. He is weak, and the burden of life is most heavy. If he does not rely on the Omnipotent One of Glory, place his trust in Him and confidently submit to Him, his conscience will always be troubled. Fruitless torments, pains and regrets will suffocate him and intoxicate him, or turn him into a beast. If you spurn this trade with its fivefold profit, in addition to being deprived of its profit, you will suffer fivefold loss.
