What is the meaning of Acts 26:8?

8 Why should it be thought a thing incredible with you, that God should raise the dead? (Acts 26:8 KJV)

William Burkitt’s Commentary

As if Apostle Paul had said, “The great point in controversy between me and you is this, Whether the dead in general shall arise? And Whether Christ, in particular, be risen from the dead? Now why should either seem incredible to you? Is it too hard for God, who made the world, upholds the world, and gives life to all living; is it too hard or difficult for him to raise the dead? If not, why should it be thought incredible or impossible?”
Learn hence, That the doctrine of the resurrection of the dead, both of the just and unjust is neither incredible nor impossible and it is neither against right reason nor true faith.
