Some people don't believe in prayer. They may not say it outright with their words, but by their actions, you can see that they don't believe prayer is really that important in one's life. Otherwise, they will pray more and encourage others to pray more. In fact, many Christians today do not pray regularly, except in church. Why? There may be many reasons. But one common reason is that they are not sure whether it is effective or not. Does God really hear our prayers?
