"After-sales service is more important than assistance before sales. It is through such service that one gets permanent customers."

God is the hardest taskmaster I have known on this earth, and he tries you through and through. And when you find that your faith is failing or your body is failing you, and you are sinking, he comes to your assistance somehow or other and proves to you that you must not lose your faith and that he is always at your beck and call, but on his terms, not on your terms. So I have found. I cannot really recall a single instance when, at the eleventh hour, he has forsaken me.
