Sometimes they put the signboard, "Goodman and Company," businessmen. The signboard is "Goodman," but he is cheating simply, from business point of view.
That kind of signboard will not help you. If you actually believe in God, then try to understand what is God. Otherwise how you can believe? If you do not know the person in whom you have to trust, how you can trust Him? ...
I say, "Trust in Him," but if I do not know that man, how I can trust? You must explain that "This man is in this way trustworthy." Otherwise what is the meaning of my trust? This science should be understood, what is God and what is trust. That you discuss thoroughly, threadbare. Otherwise how you will be able to preach?
Ask all questions. I will answer. But you must be thoroughly conversant that there is need of God and everyone must trust in God. This is the standard of civilization. God is there. Without God, there cannot be anything existing. This is first point. And we must trust in God.
