Challenging the truthfulness of the resurrection of Christ, and even the existence of God, is a common dialog in agnostic and atheist circles. A central theme to these debates is that anything about God can be neither proved nor disproved. Now, at face value, this would then seem to be a matter of personal inclination - I can choose to affirm or deny God, the Virgin Birth, the Resurrection, the raising of Lazarus, even the biblical miracles.
Yet God is not one to be proven, rather He is known through experience. Would it surprise you to know, that in the context of this argument ... the disciples chose to deny the resurrection? Based purely upon personal inclination, they chose to NOT believe in Christ. That is, until Easter became real.
