The Gospels End With the Gospel of John, Verse 3

Jesus stuck around for 40 days because remember, I mean Jesus was brutalized on the cross. He rose from the dead three days later and still His boys were like, there's no way. So these guys needed some reassuring. Their faith had been jostled to say the least. The Bible is the infallible word of God. It's not going anywhere. John said that heaven and earth will pass away before my words pass away. And I believe that.
