1 Corinthians 13:13
Will you also look upon those who have become rich but not of God, that you may learn how they employed their wealth? Behold him in the parable of Lazarus, how he imparted not so much as a share of his crumbs. Behold Ahab, how not even the vineyard is free from his extortion: behold Gehazi: behold all such. Thus they on the one hand who make just acquisitions, as having received from God, spend on the commands of God: but they who in act of acquiring offend God, in the expending also do the same: consuming it on harlots and parasites, or burying and shutting it up, but laying out nothing upon the poor.
“And wherefore,” says one, “does God suffer such men to be rich?” Because He is long-suffering: because He would bring us to repentance; because He has prepared hell; because “He has appointed a day in which He is to judge the world.” Whereas did He use at once to punish them that are rich and not virtuously, Zacchæus would not have had an appointed time for repentance, so as even to restore fourfold whatever he had unjustly taken, and to add half of his goods; nor Matthew, to be converted and become an Apostle, taken off as he would have been before the due season; nor yet many other such. Therefore does He bear with them, calling all to repentance. But if they will not, but continue in the same, they shall hear Paul saying that after their hardness and impenitent heart they treasure up unto themselves wrath against the day of wrath, and revelation, and righteous judgment of God: which wrath that we may escape, let us become rich with the riches of heaven, and follow after the laudable sort of poverty. For thus shall we obtain also the good things to come: the which may we all obtain through the grace and mercy of our Lord Jesus Christ, with Whom to the Father, with the Holy Ghost, be glory, power, and honor, now and for ever, and world without end. Amen.
