A dedicated Christian should always have the attitude of Jesus Christ, who said: “My food is for me to do the will of him that sent me and to finish his work.” (John 4:34) A principal part of God’s work for Jesus on earth was to preach the kingdom of God, and to lay the foundation for a preaching organization to carry on this activity after his death. That was God’s will for him, and Jesus faithfully did it.​—Luke 4:43; John 17:4.

12. (a) How is the preaching work to be done? (b) Does Jesus’ command to “make disciples” apply to all Christians?

¹² Jesus Christ set the example in performing the ministry. He preached everywhere, in the cities and villages, in homes and in public places​—even to a woman at a wellside. (John 4:7, 21-24) A true Christian today will follow Jesus’ example. He will preach at every opportunity.
