Here are three interesting proofs of the Resurrection.
The most persuasive is omitted which is that ten mouse-like Apostles (not John) ran away and hid in dark rooms on Good Friday. Then, they must have seen something which changed them into 'lions of courage' who preached openly, at the risk of their lives in the streets, within weeks.
Clearly, their fear of death had evaporated. Theirs was the act - spearheaded by traitorous but forgiven Peter - that transformed human history.
What changed them? Christians believe they saw the Risen Christ who, once risen, filled them with His Spirit.
