With all due respect, I'm more inclined to believe the broad consensus of the philosophical community than online boasts yet to be explained in any serious detail.
Essentially, Swinburne is arguing that properties associated with the Christian God, like omnipotence, ombnibenevolence, Trinity, and incarnation in the person of Jesus of Nazareth are the sorts of properties we could logically expect God to have. He does spend a bit of time arguing for the historicity of the Resurrection, but that's pretty much the extent to which he references the Bible.
