Does God Still Give Special/Specific "Calling"?

I know in my fellowship this sort of stuff is relegated to the apostles and special "Bible Times" people. This is worth considering. The author is dealing with a myths about mission.
When replying to "God no longer calls his people" he writes.

He was thirty years old when he heard an interviewer had come to his country. The interviewer was trying to understand how it was possible for men and women in this particular country to come to faith in Christ, given the severe persecution that was so prevalent. The man’s people group exceeded twenty-six million at the time— and at that time, outsiders were aware of only three believers.

The man arranged to meet with the interviewer. He shared about earlier days. lie talked about dis harmony in his marriage. He explained that his children were sick and weak, his crops simply refused to grow and his livestock multi plied erratically.

True to his folk-Muslim culture, he went to the spiritualist for ad vice. After describing the problems in his life, he received this word: “I will sacrifice a chicken on your be half. You are to return home, Fast and meditate for three days and three nights. On the third night, an answer to your problems will come,”
The man did exactly as he was instructed. He told the interview er, “On the third night, a voice without a body came to me, saying
‘Find Jesus, find the good news:”

The man knew nothing but Islam. lie had nothing but an oral Quran. He had never met a Christian. He had never heard of a Bible. Lie did not know whether “Jesus” was a fruit, a vegetable or a rock. He did, however, want the good news he had been told about. This voice instructed him to go to a particular city about five hours away. It was a city the man had never visited. The voice instructed him to ask the first two men he met in the city to direct him to a certain street. Then, he was to search for a door marked with certain numbers.

This man, without informing
his wife or children, left his village the next day. lie walked five hours over the mountains, lie arrived at the city, and he asked the first two men he saw to direct him to a certain Street. He walked down that street until he saw the door marked with the correct number He knocked on the door until an older gentleman opened it. “What do you want?” the older man asked. The young man answered, “I have come to find Jesus and the good news!”
A hand shot out and pulled the young man into the house. “You Muslims must think I am idiot to fall for something like this!” the older man cried. But the young man replied, “Sir, I do not know if you are an idiot or not, but this is why I have come. I have been told to come.”

Over the next hour, the young man told his story. God had led this man to the home of one of the three believers known among that people group at the time! Patiently, this older man shared the story of Jesus with the young man until the good news became his own. The young man returned to his village. Over time, his wife saw the change in his life and she too became a believer. His children regained their health; his crops and livestock prospered. Faith broke out in his village.
