Romans 9:14-

in order that he might make known the riches of his glory upon vessels of mercy, which he prepared beforehand for glory,

10. Why has Jehovah tolerated the wicked for the past 1,900 years?

¹⁰ During the more than 1,900 years since Jesus’ resurrection, Jehovah has tolerated further the “vessels of wrath,” holding off their destruction. Why? For one thing, because he has been preparing those who are to be associated with Jesus Christ in his heavenly Kingdom. These are 144,000 in number, and they are the “vessels of mercy” spoken of by the apostle Paul. First, individuals from among the Jews were invited to make up this heavenly class. Later, God invited people of the Gentile nations. Jehovah has not forced any of these to serve him. But from among those who responded appreciatively to his loving provisions, he gave some the privilege of being corulers with his Son in the heavenly Kingdom. The preparation of that heavenly class is now nearly complete.​—Luke 22:29; Revelation 14:1-4.
