A simple, conventional answer may be that we pray because our forefathers have been praying and told us to pray, just as we tell our children to pray. Or that we pray because God has asked us to pray. But for many people who are sincerely searching for a more meaningful answer, this may not be satisfactory. First of all, God has given us freedom of choice for everything, including prayer. So we do not have to pray if we do not want to. In fact, in good times, most of us don’t. Only when some personal tragedy strikes or when we reach old age that many of us start praying regularly. For example, consider a plane full of people about to crash. In this helpless situation, every one will be praying for life and survival. If the situation seems completely hopeless, and they realize that they are going to loose their lives, people will be praying for God’s mercy, forgiveness, His pleasure, and personal salvation in the hereafter. But nevertheless, everyone will be trying his/her best to survive until the very end. This instinct of self-survival is inherent in every living being, including humans. Other beings have defense mechanisms given by God for their survival.
