Why does God keep silent to some people even though they cry to Him intensely?

[Question by Dr. Sheshadri Thiruvenkadam (Balaji).] A diabetic patient cries before a doctor to get a sweet to eat. The doctor has infinite number of sweets but he does not care at all to give one to the patient. You cry before God, who is the Divine Father (Creator of all the souls) to give some wealth or to solve some problem. If He helps you, there will not be even a trace of any personal loss to Him. Neither is His wealth finite nor is His power finite. His love for souls is not limited either. The only factor that guides God is seeing the future position of the soul after God helps the soul. If after receiving God’s help, you are going to reach the climax of ego, God will prefer to keep silent and not answer your cries. Because He knows that after His help, you will fall down even from your present level and then you will cry again before Him to lift you up. If the doctor gives you the sweet, the level of your blood sugar may go up and the emergent treatment required, is also the responsibility of the same doctor. Hence, the doctor will not give you the sweet. He may give the sweet if the doctor is confident of your health. Sometimes, the doctor gives you the sweet and then also conducts the emergent treatment to show you the truth. This is when you scold the doctor and call him unkind. The response of the doctor lies on his analysis of the situation and it is not the subject of the patient at all. You must have faith in the doctor (God) that any response from Him is for your good alone. You must also know that the patient is ignorant of his own real welfare.
