Here's two guys,
Guy 1: Last Friday, before teaching Jana from her new Slovak Book of Mormon, we were searching for members whom the leaders of the congregation, the ward council, did not know. We were at a point where we were sort of discouraged in finding new people to teach and baptise. Being inspired to visit a particular house of one of these lost members, we knocked on the door. Of course no one answered! But we were certain that the Spirit prompted us to knock on her door! What happened? We decided to ask her neighbors about her whereabouts and one of them said that she moved nine years ago. We were prompted to teach the Restoration of the Gospel of Jesus Christ and the neighbor said, "So, you ain't cops. I'm looking for a church to join." We told her that, no, we are not cops, and that we are missionaries from the Church that she should join. It was apparent that the prompting of the Holy Ghost was real when she accepted the invitation to come to church next Sunday and we found a new person to teach.
Guy 2: Last Wednesday, while still in the same rut that we were in regarding the number of people to teach, we gave a card to a young boy on the street. He asked if the person on the card was Jesus. We said yes and taught him the Restoration of the Gospel of Jesus Christ. He invited his seven other friends to join. We taught them as well. As a result, we told them that we'd come back on Saturday. On Saturday, we received the opportunity to teach the same lesson to their parents, who invited us back next Saturday. We also taught seven other lessons that day. God rescued us from the rut that we were in.
The lesson that I learned was Exodus 14:13 and Moroni 7:33; again, this is not my work, but God's.
