As simple as it may be, the logical fallacy of praying was one of my first clicks. After some time praying in a mechanical way I started to analyze it logically. Here is the reasoning:
Lets suppose that two witnesses in different parts of the world pray to Jeohovah at the same time asking for protection before going to service field. What are the possible outcomes?
1) Both come home safely after service field.
Possible Conclusions: Jehovah protected both; Jehovah protected only one of them and the other was lucky; both got lucky.
2) One of them comes home safe but the other one get robbed.
Possible Conclusions: Jehovah protected one but not the other (Why???); Jehovah did not intervened on both cases, letting one be robbed and the other not (Why???).
3) Both get robbed.
Possible Conclusions: Jehovah did not intervened on both cases (Why???).
Here are my thoughts:
The answer to a prayer is nothing more than selective human inference.
In case #1, one or both witnesses may assume that God answered their prayers, but thinking on the side of the robber, God would have to change his mind or the events in his life so he wouldn't have the chance to stole them, so God is interfering in his free will. (Do we have free will?)
In case #2, the witness that returned home safely may assume that God answered her prayer, but it implicates that for some unknown reason God didn't do the same for the other witness, which means God may have different plans for us. (Do we have free will?)
And considering all the hypothesis, if we assume that God did not intervene in any case, why do we pray for his protection? (Do God answer our prayers?)
If we pray, but its up to him to decide whether he will protect us or not, do we command our lives? Do the other person involved in the thief, car accident, etc, command her life? (Do we have free will?)
So I got my wife going in circles when I exposed this to her. The same will happen with every witness.
