Suppose a person owns a shop to earn his livelihood. He goes to the shop everyday to maintain sales and customers. Now, what will happen if he doesn't go to the shop and open it for one day? He will suffer some loss. What if he doesn't go for two, three, four or five days? He will suffer a big loss. Eventually he will become a failure if he continues not to go.
As Muslims, we are to live in this world as presenters of Islam. Our job is to practice Islam fully and show the whole humanity what Islam is. But, many of us have not been fulfilling our duties for 20 years! Some for 60 years! What is the loss for not doing our job for so many years? The whole world is affected. Most Non Muslims are dieing as Non Muslims and Muslims are dieing without iman and repentance. Don't be happy by seeing one or two people becoming Muslims. In the countries of Africa, South America, Central America, etc, millions of Muslims have been leaving Islam for some money and food. If us Muslims did our assigned job, then no one would remain hungry in this world. If we paid our due zakah, then no one would buy the hell fire with few dollars from the missionaries.
