On the basis of such a powerfully documented resurrection hope, Paul could assure the Athenians: “God . . . has set a day in which he purposes to judge the inhabited earth in righteousness by a man whom he has appointed, and he has furnished a guarantee to all men in that he has resurrected him from the dead.”​—Acts 17:30, 31.

Yes, the resurrection of Jesus is the ultimate guarantee of the validity of the resurrection hope.

After Paul’s audience on Mars’ Hill heard his testimony about “a resurrection of the dead,” it was split into three groups: “Some began to mock, while others said: ‘We will hear you about this even another time.’ . . . But some men joined themselves to him and became believers.”​—Acts 17:32-34.
