Seven years ago, I preached the Gospel to one of my friends, Sister W, who showed up several times in the church and then never appeared again. She had run a law firm for more than a decade, together with her husband and son, and the business went on fairly well. Then, the family continued to invest in the financial market, shopping malls, and real estate projects of our town. As all their business thrived, they lived a busy life. However, two years ago, after we hadn't seen each other for five years, Sister W suddenly came back to the church and asked to be baptized as soon as possible.
