Are Biblical miracles "undeniable"?

Part of the MacArthurite schtick is to claim that Biblical miracles are "undeniable," in contrast to reported modern miracles. Yet in the NT we have examples of both outsiders and churchgoers who deny the Resurrection. 

and of this he has given assurance to all by raising him from the dead.” 32 Now when they heard of the resurrection of the dead, some mocked (Acts 17:31-32). 

12 Now if Christ is proclaimed as raised from the dead, how can some of you say that there is no resurrection of the dead? (1 Cor 15:12).

So, by MacArthurite standards, does that mean the Resurrection doesn't count as a real miracle?
