Jesus told us to “go . . . make disciples of people of all the nations.” (Matt. 28:19) And in addition to teaching a student what Jesus requires of his disciples, we need to help the student come to know how to live as a true Christian. We must patiently assist him as he struggles to put Bible principles into practice. Some are able to change their thinking and habits in just a few months; others take longer. A missionary in Peru had an experience that illustrates the benefit of being patient. “I had studied two books with a Bible student named Raúl,” says the missionary. “But he still faced serious challenges in his life. He had a stormy marriage, used foul language, and had children who found it difficult to respect him. He came to the meetings regularly, so I continued visiting him to help him and his family. More than three years after I met him, he qualified for baptism.” w19.07 15 ¶3; 19 ¶15-17
