According to proponents of the Skeptic's Prayer, how much detail and specificity can be added to its conditions and expectations?

The "Skeptic's Prayer" is introduced on page 411 of [*Handbook of Catholic Apologetics: Reasoned Answers to Questions of Faith*](https://www.amazon.com/Handbook-Catholic-Apologetics-Reasoned-Questions/dp/1586172794) , by Peter Kreeft & Fr. Ronald Tacelli. > ### The Skeptic's Prayer > > This claim---that all seekers find---is testable by experience, by > experiment. If you are an honest scientist, here is a way to find out > whether Christianity is true or not. Perform the relevant experiment. > To test the hypothesis that someone is behind the door, knock. To test > the Christian hypothesis that Christ is behind the door, knock. > > How do you knock? Pray! Tell Christ you are seeking the > truth---seeking *him*, if he is the truth. Ask him to fulfill his > promise that all who seek him will find him. In his own time, of course. He > promised that you would find, but he didn't promise a schedule. He's a > lover, not a train. > > But---you may reply---I don't know whether Christ is God. I don't even > know whether there is a God. That's all right; you can pray the > prayer of the skeptic: > > > God, I don't know whether you even exist. I'm a skeptic. I doubt. I think you may be only a myth. But I'm not certain (at least when I'm > completely honest with myself). So, if you do exist, and if you really > did promise to reward all seekers, you must be hearing me now. So I > hereby declare myself a seeker, a seeker of the truth, whatever it is and wherever it is. I want to know the truth and live the truth. If you are the truth, > please help me. > > If Christianity is true, He will. Such a prayer constitutes a > scientifically fair test of the Christian "hypothesis"---that is, if > you do not put unfair restrictions on God, like demanding a miracle > (your way, not his) or certainty by tomorrow (your time, not his). The > demand that God act like your servant is hardly a scientifically fair > test of the hypothesis that there is a God who is your King. > > But all this King asks for at first is honesty, not faking a faith you > do not have. Honesty is a choice of the will---the choice to seek the > truth no matter what or where. This is the most momentous choice you > can make. It is the choice of light over darkness, ultimately heaven > over hell. > > Honesty is infinitely more momentous than we often think. It is also > much harder than we think. Our culture trivializes honesty into merely > "sharing your feelings", telling others about the state of our nerve > ends. That's not the opposite of dishonesty, that's just the opposite > of *shame* or shyness. Shallow honesty seeks "sharing"; deep honesty > seeks truth. Shallow honesty stands in the presence of others; deep > honesty stands in the presence of God. An often-raised critique of this prayer's presentation is its perceived vagueness regarding conditions and expectations (see examples of critiques [here](https://philosophy.stackexchange.com/q/108053/66156) and [here](https://infidels.org/library/modern/robby-berry-skeprayr/)) . According to proponents of this form of prayer, how much additional specificity and detail can be added beyond what Peter Kreeft and Fr. Ronald Tacelli have presented? In particular, I'm interested in the following aspects: *Conditions* For the Skeptic's Prayer to be effective, are there unstated implicit conditions beyond those mentioned by Peter and Ronald? For instance: - Is a single invocation sufficient, or does it require daily repetition over a few days, multiple times a day for an extended period, or even years or decades? The clarification on this aspect is not provided by Peter and Ronald. At a minimum, it seems they endorse trying the prayer at least once. However, they provide no guidance on frequency, intensity, or similar factors. - Are there thresholds to the level of skepticism a person must have before attempting the prayer? Can one be "too skeptical" for the prayer's effectiveness, and if so, are there strategies to overcome this limitation? - Is the skeptic supposed to undertake additional practices during the Skeptic's Prayer "experiment," like attending specific church services, fasting, reading the Bible, studying natural theology, or anything else? Or is merely praying for a few minutes sufficient, with no specified changes to one's daily life? While Peter and Ronald overlook this aspect, I presume it holds significant importance. *Expectations* How explicit can expectations be in the Skeptic's Prayer "experiment"? What should the seeker anticipate? Is an event expected, and if so, will it be clear and unmistakable? Can specific examples of this event be given to enhance the expectation's specificity, clarity, and detail? Peter and Ronald caution against expecting miracles, but what reasonable outcome can the seeker envision in their mind as something to anticipate with hopeful expectation?
