When you find your faith being challenged, don't hide from the questions before you. When you have trouble believing, don't deceive yourself or lie to others. State the problem and give it deep and serious thought. Discuss it with people of mature faith. Open your eyes to the many things that declare God in your world, and allow faith to confront and conquer doubt.
Christian faith has no challenge that is intellectually invincible.
At the same time, our limited perspective does not allow us to find every element to the full answer about evil we would like to have.
