Last couple of years, one thing I promoted the most is Operation Cornelius. Members of the church ought to have a burning burden to preach the gospel to their blood relatives. Whenever there is a chance to visit relatives in homeland, never waste any chance to bear witness to the relatives and friends, even strangers.
One brother went home one summer and led a few dozen relatives to Christ. Another sister went back to see her father one last time on earth, she led a few to Christ while in the hospital. Still another sister shared the gospel with her relatives over the phone, leading a few to Christ. Another brother led two neighbors on the airplane in the high sky to Christ. The story goes on.
