A couple days ago, my brother asked an interesting question. I feel like most of us think that the most important question everyone should answer is, "What do you believe?" but maybe it's not. It is a question everyone should answer, but maybe the bigger question is, "Why do you believe?"
Everyone has an answer to the first question, whether they think they do or not. They might believe that it doesn't matter what you believe, or they might have an actual belief. The second question is a little more tricky though. Sure, you might know what you believe, but how about why? Do you have legitimate reasons? Evidence?
Consider the answer not only I began to answer, but also many other Christians might answer: "I know it in my heart."
