Feeling a sense of shortcoming is a sign of good

Question:
When we hear some of the sermons, I feel weak, or I feel a tightness in my chest, and I feel that I am falling short in my worship. I become sad and feel that I am far from the deeds of the righteous. What does this mean?

Answer:
This is one of the signs of good. The one who feels that he is falling short, this is a sign of good. Praise Allah the Exalted, praise Him and strive. Strive against your self for good as long as you know that you are falling short and that you are far from the deeds of the righteous. So hasten and rush to do good, and strive against your self until you catch up with the righteous in your prayer, your fasting, your remembrance of Allah, and all the matters that Allah has prescribed. The calamity is heedlessness, turning away, and not feeling anything; that is the calamity. As for the one who feels tightness and pain from his shortcoming, these are signs of good that Allah will guide him and help him.
