Is the evidence for Jesus’ resurrection just as obvious as 2 + 2 = 4? No, it cannot be, for mathematics is simply the joining of two concepts in the mind. Nor is it like science, whose experiments can be repeated. The evidence for the Resurrection is rooted in proper historical investigation based on accepted rules of manuscript evidence. The evidence is enough for the honest doubter, but not enough for the dishonest one.
