No one can irrefutably “prove” Christianity is true or not true. That’s because it’s about history and theology, not science, so not verifiable through a reproducible experiment. But just because we can’t replicate something doesn’t mean it didn’t happen.
Actually, it’s worth noting that it probably takes more faith to not believe. That’s because there are so many arguments for the existence of God in general (e.g., cosmological, ontological, design) and so much evidence for the truth of Christianity in particular (e.g., manuscripts, archaeology, changed lives). To reject Christian belief may actually require more faith in some alternative explanation.
Here is a worthy question: If the arguments and evidence against Christian faith are no greater than the arguments and evidence for it, why not choose the better thing?
Until every church disciples every man…
