Disciples are called to learn God's way now so they can teach it as kings and priests in the Millennium. Christ's commission to make disciples of all nations, baptizing them and teaching them to observe all He commanded, makes the church responsible to announce the good news and teach it. The church is the kingdom in embryo, pioneering the only true solution: joyful, voluntary submission to God's laws. A person cannot teach until he has first been a learner, so every disciple is now in training for rulership under Christ. A good disciple-teacher fears the Lord, since wisdom begins there, and trusts God rather than leaning on human reasoning. He is a wise learner who approaches God's Word with meekness, digests it, lives by it before talking about it, and keeps growing in grace and knowledge. He sets a good example, being swift to hear, slow to speak and slow to wrath. He uses authority with self-control, never with a sense of superiority, and communicates humbly and clearly. He is patient, because patience is a fruit of God's Spirit and reflects God's patience with us. He shows mercy and loving-kindness, as Christ does. Jesus, the supreme Teacher, is the model, and His authority came from the Father. Disciples also serve as ambassadors for Christ, teaching by example, by order and unity among God's people, and by solving problems with God's way of life, so that the earth may be filled with the knowledge of the Lord.
