The atheist has a problem with both answered and unanswered prayer. Here’s a scenario that no doubt happens daily somewhere in the world. A young boy becomes deathly ill. The entire family gathers for prayer. However, despite earnest and sincere prayer, the child tragically dies. Their explanation for the death is that God took him to heaven because He wanted the child there. That’s seen by the atheist as "unanswered prayer." Or the child miraculously makes a recovery, which the family hails as an evident miracle. God obviously answered the family’s prayers by saving the child from death. The atheist maintains that it wasn’t answered prayer but that the child recovered because his body healed itself.
Was the recovery a miracle? Perhaps. Then again, perhaps it wasn’t. Only God knows. The fact is that we have no idea what happened. However, one thing we do know is that answered or unanswered prayer has nothing to do with God’s existence. Let me explain.
My wife has a Dodge Caravan. Let’s say it has a problem. What would be my intellectual capacity if I concluded that it had no manufacturer simply because I couldn’t contact them about the dilemma? The fact of their existence has nothing to do with whether or not they return my calls. Neither does God’s existence have anything to do with the fact that there are those who have experienced miracles, seen visions, or supposedly heard His voice. The sun doesn’t exist because we see its light, or because we feel its warmth. Its existence has nothing to do with any human testimony. Nor does it cease to exist because a blind man is not aware of its reality, or because it becomes cloudy, or the night falls. The sun exists, period.
God’s existence isn’t dependent on the Bible or its authenticity, the existence of the Church, the prophets, or even creation. God existed before the Scriptures were penned, before creation came into existence, and even if the Bible was proved to be fraudulent, God would still exist.
