"The agony of questions I cannot answer"

I heard this quote on the radio,  I think it was Dennis Rainey quoting Tom Skinner:

I spent a long time trying to come to grips with my doubts, when suddenly I realized I had better come to grips with what I believe. I have since moved from the agony of questions that I cannot answer, to the reality of answers that I cannot escape . . . and it's a great relief.
