It is perilous to separate thinking rightly, from acting rightly. He is already half false who speculates on truth and does not do it. The penalty paid by him who speculates on truth without doing it, is, that by degrees the very truth he holds becomes a falsehood.
The pharisees minded what God spoke, but not what He intended. They were busy in the outward work of the hand, but incurious of the affections and choice of the heart. So God was served in the letter, they did not much inquire into His purpose; and therefore they were curious to wash their hands, but cared not to purify their hearts.
Do not burn false fire upon God's altar; do not pose and pretend, either to Him or to yourself, in your religious exercises; do not say more than you mean, or use exaggerated language that goes beyond the facts, when speaking to Him whose word is truth.
They that cry down moral honesty, cry down that which is a great part of my religion, my duty toward God, and my duty toward man. What care I to see a man run after a sermon, if he cozens and cheats as soon as he comes home. On the other side, morality must not be without religion; for if so, it may change, as I see convenience.
