I don't think Christians use Pascal's Wager for their own benefit. I think they use it for the benefit of those who claim to have all kinds of logical reasons why they should not accept God in Christ.
Have you ever used an argument based on Pascal's wager in an attempt to persuade a non-believer, or even a person who you felt was ready to believe? If so, what was the result?
As a Christian, the argument appears to me to be complete nonsense and likely to be a complete turnoff. I know that I could not present it with a straight face.
If in fact, Christians are not motivated by such arguments, and you seem to be saying that, then how can your goal be to win converts with such an argument? Would that person then become the first Christian ever who was motivated by the argument?

I have never met a man so ignorant that I couldn't learn something from him. Galileo Galilei
If there is no struggle, there is no progress. Those who profess to favor freedom, and deprecate agitation, are men who want crops without plowing up the ground, they want rain without thunder and lightning. Frederick Douglass
