My take on tithing in America is that it's a middle-class way of robbing God. Tithing to the church and spending the rest on your family is not a Christian goal. It's a diversion. The real issue is: How shall we use God's trust fund-namely, all we have-for His glory? In a world with so much misery, what lifestyle should we call our people to live? What example are we setting?
John PiperI recall hearing one of my professors in seminary say that one of the best tests of a person's theology was the effect it has on one's prayers.
John PiperThe suffering of sickness and the suffering of persecution have this in common: they are both intended by Satan for the destruction of our faith, and governed by God for the purifying of our faith... Christ sovereignly accomplishes His loving, purifying purpose, by overruling Satan's destructive attempts. Satan is always aiming to destroy our faith; but Christ magnifies His power in weakness.
John PiperIf gratitude is not rooted in the beauty of God before the gift, it is probably disguised idolatry. May God grant us a heart to delight in him for who he is so that all our gratitude for his gifts will be the echo of our joy in the excellency of the Giver!
John PiperOur obedience is God's pleasure when it proves that God is our treasure. This is good news, because it means very simply that the command to obey is the command to be happy in God. The commandments of God are only as hard to obey as the promises of God are hard to believe. The Word of God is only as hard to obey as the beauty of God is hard to cherish.
John PiperWhat is sin? It is the glory of God not honored. The holiness of God not reverenced. The greatness of God not admired. The power of God not praised. The truth of God not sought. The wisdom of God not esteemed. The beauty of God not treasured. The goodness of God not savored. The faithfulness of God not trusted. The commandments of God not obeyed. The justice of God not respected. The wrath of God not feared. The grace of God not cherished. The presence of God not prized. The person of God not loved. That is sin.
