Listen to the testimonies of a variety of witnesses in a courtroom concerning any event and you will hear various details presented about the same event. This is not inconsistency, but rather gives credibility to the accounts as each person expresses or highlights things a little differently from their own perspective or what stood out to them, yet with a consistency concerning the main theme of the event. If every gospel account was precisely identical down to the detail, then I'd say you would have reason to wonder about the truthfulness of the accounts.
The scriptures state that Jesus appeared alive to more than 500 people, on twelve separate occasions, even talking, walking, and eating with some of these people. This does not sound like only mystical visions to me. In the case of Thomas, Jesus told him to touch His hands and side were He had been wounded. And He specifically clarified to the disciples He was risen bodily and not just a spirit.
And He said to them, “Why are you troubled? And why do doubts arise in your hearts? Behold My hands and My feet, that it is I Myself. Handle Me and see, for a spirit does not have flesh and bones as you see I have.”
When He had said this, He showed them His hands and His feet. But while they still did not believe for joy, and marveled, He said to them, “Have you any food here?” So they gave Him a piece of a broiled fish and some honeycomb. 43 And He took it and ate in their presence. Luke 24: 38-42
I conclude the Bible is reliable because it makes sense and is set in historical context, provides real names of people and places and other details which the writers including for the very purpose of giving validity to their testimonies. There were plenty of those around who were hostile to Jesus and the resurrection who could have very easily disproved the gospel accounts, were they not true and the early church would never have gotten started. But the resurrection of Christ was not disproved then because it did take place and even the enemies of Jesus knew it had, so they tried to hide it and then began the persecution of the first Jewish followers of Christ.
I am a born again believer. That means that at one time I did not understand, nor trust in Christ or the Bible. But at the point I did see my need for a Savior and believe it was Jesus, my eyes were opened to the scriptures, their accuracy, truthfulness, and the theme of God's redemption throughout.
