RE.: "I know it's easy for you to believe in a God. But I've suffered more than you."

You've suffered more (maybe)... so what?

Since when does the magnitude of a person's individual suffering alter the validity of their argument? The measuring scale game has no worth nor does it garner interest from the objective.  

Assumptions

When this kind of statement is made, huge emotionally-driven assumptions are being made. A) That belief in God is "easy" and B) that the person making the statement knows how much suffering the other person, on the receiving end, has endured. It also implies a rather gross pre-conception of the god in question.

Belief has its appeal.

If one conducted a survey, they will likely find that, historically, people have been drawn to faith both from a life of relative ease and of cruelty. For an example of the latter (just to dismantle some of the assumptions made in the entitled statement), the Black Church in the south. Or the crucified apostles of Jesus. Or Jesus.

Perhaps, for these people, belief is grounded less on emotion. The whole 'solid rock' v. 'sinking sand' thing.

The bottom line is, let's make sure we're talking about the same god. It doesn't matter what kind of God you would like to serve because that doesn't determine what kind of god you ultimately submit to. Ease and comfort don't register high on my god's priority list. So why should they on ours? Because what matters in light of eternity is not our revenue nor our pains, but what transformation, underneath, we experience in the process. Why go for gold when we could go for life and the abundance afterwards?
