I can no longer believe in prayers/personal relationships with God.
As expressed in the title, I can't believe in these things precisely because of the problem of evil. How can God, if all-powerful, loving, and merciful, answer prayers (as well as requests) and not answer the prayers of other people, such as children who plead for food/better conditions?
To me, it seems like mere luck, because if it's true, God has his favorites and is sadistic and cruel.
Furthermore, if creation is perfect and planned by him ,why do we pray to correct God's plans?
