The teaching of Jesus is clear. Even if someone were to see a sign as miraculous as someone coming back from the dead, they could still waiver in unbelief. Jesus is not, however, denying the use of evidence in supporting belief in God. What he is saying is that evidence has its limits on people. Sometimes, evidence helps people believe. Other times, a person’s will is in a negative disposition such that the presented evidence smatters against the brick wall of a person’s mind like a rotten tomato. — Eric Chabot (from, A Look at the Insufficient Evidence Objection to the Resurrection of Jesus)
