All human life is based upon faith. No one can subsist for a single moment without faith. Here is a small example. A man lays the foundation stone for a house today. If he does not have the confidence that by next year this house will be ready and that he would live till next year, will he seek to build a house at all? One gets up in the morning, takes up a bag to go to the market to buy vegetables. Without the belief that he will return home after buying the vegetables from the market, will he leave the house at all? From the time of waking till going to sleep, everything that man does every moment is based on faith and confidence.
