Christianity is constituted so that warrant for its faith is based on the premise that God manifests that He is the living God, including that those who believe on Him out of a honest and contrite heart realize effects in heart and life which correspond to His promises, and though this includes trials, it also includes positive things which defy reasonable naturalistic explanations, though my experience with atheists is they simply cannot allow any possibility even for any supernatural explanations.
While there certainly can be natural reasons for claims (yet God uses nature) as well as fabrications, there are also those which testify more clearly to a supernatural cause. Watch many here: http://www.cbn.com/700club/features/Amazing/ (which does not sanction everything that Robertson says).
Add to such the thousands of classical hymns about a personal relationship with the Lord Jesus, which i think is unique in scope and depth.
As regards “that NONE of his disciples were ever capable of writing,” this may indicate you simply read atheistic type material. In contrast, see scholars here: http://bible.org/seriespage/did-some-disciples-take-notes-during-jesus%E2%80%99-ministry
Jesus answered, “The work of God is this: to believe in the one he has sent.”
1 John 3:21-24
Dear friends, if our hearts do not condemn us, we have confidence before God and receive from him anything we ask, because we keep his commands and do what pleases him. And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us. The one who keeps God’s commands lives in him, and he in them. And this is how we know that he lives in us: We know it by the Spirit he gave us.
