wegs,
How is this concept of God exclusive to Christianity?
Christians tend to follow the NT, as their beliefs are drawn from it.
Did he specifically mention a specific God which is only believed in by Christian's in his wager?

No, but it stemmed from Christian principles. Putting it a different way, Pascal's Wager doesn't indicate which God is the ''one, true God,'' but it may be assumed that it's God as defined in the NT.
