Even Thomas was eager to see, eager to be persuaded. If we had been standing outside Joseph of Arimathea's tomb and were cynical or negative toward Jesus, there is no indication that we would have seen anything at all except some women coming with oils to anoint the body. Even now, the most powerful appearances of divine representatives in vision and voice are often dismissed by others, or even by the persons to whom they occur, as hallucination or some other defective form of perception. But ultimately, even if the supposed encounter has been dramatic, it takes an act of faith by the person who experienced it to make it function in his or her life. This is not meant to endorse faith that refuses to dialogue with reality.
Reality presents questions to faith.
If the believer refuses to ask them, faith becomes clogged by dogmatism and denial. Simply to assert religious dogma in the face of real life can isolate one from God and the Holy Spirit. What many people call faith is nothing but a stubborn refusal to look at reality. Faith is the opposite of refusal. It is the absolute willingness to look at reality in the belief that God can still be found, no matter what happens or what appears.
