There is an answer to every call; those who call on God, to them God comes.

Bowl of Saki, by Hazrat Inayat Khan
Commentary by Pir-o-Murshid Inayat Khan:

There is no doubt that if an individual or a multitude believe that a teacher or a reformer will come, he will surely come to them. Similarly, in the case of those who do not believe that any teacher or reformer will come, to them he will not come. To those who expect the Teacher to be a man, a man will bring the message; to those who expect the Teacher to be a woman, a woman must deliver it. To those who call on God, God comes. To those who knock at the door of Satan, Satan answers. There is an answer to every call.

There is nothing that you ask that this universe will not answer. For it is the nature of this universe to answer your soul's call. ... When a person seeks for something in the universe and he cannot find it, it is not true that it is not there. The fact is that he does not see it.

He who is always there has said, 'I am Alpha and Omega. I exist every moment. When you call me, I am there. Knock at the door, and I will answer you.' And those whose eyes are open do not need to go to a church and look at a picture or statue of the Lord. In the eyes of every infant, in the smile of every innocent child, they receive the blessing of Christ.

It only means changing one's outlook on life, and recognizing the divine in man. But man has ignored the divine spirit that manifests in humanity, and always prefers an idol, a painting, a picture, to the living God, who is constantly before him. For the sage, the seer, the saint, and the yogi who begin to see the master, and see him living, there is no place where he cannot be seen. Then everywhere the beloved master is ready to answer the cry of the soul coming from friend, father or teacher. And if we go a little further forward, we will find that the teacher speaks aloud, not only through living beings, but through nature. If the eyes and ears are open, the leaves of the trees become as pages of the Bible. If the heart is alive, the whole life becomes one single vision of His sublime beauty, speaking to us at every moment.
