Few obstacles keep people away from belief in God like the problem of evil. How can we claim that God is love when every day there are people dying in terrible accidents, children being abused, and every other kind of suffering imaginable? There is nothing more devastating than putting total faith in God only for the worst to happen anyways.
To top it off, Christians have the audacity to ask God for help with the most trivial things—like finding their car keys or doing well in a job interview. Why would God care about your pathetic issues when there are kids dying somewhere else in the world?
