Only one who spends for the cause of God finds God. When he finds Him, he comes into possession of a light which leads him on to the straight and undeviating path to paradise—the final destination of a true believer. On the other hand, one who wants God without paying this price, remains in darkness forever. ‘Spending for God’s cause’ relates here to any kind of sacrifice made for the sake of God, and not merely to spending one’s wealth: for instance, devoting one’s life to the cause of God; sacrificing one’s material interests and considerations to go ahead along God’s path. When one accepts an ideology at the cost of sacrifice, then it shows that one is sincere about it. Sincerity is a matter of great importance, for, regardless of the issue, it is only when one is sincere that one can delve deeply into the subject; then all its secrets are laid bare before one. It is this element of sincerity that enables a real relationship to be created between the man and his goal. In consequence, all the aspects of that goal are revealed to him.
