18 And Jesus came and said to them, "All authority
in heaven and on earth has been given to me. 19 Go therefore and make
disciples of all nations, baptizing them in the name of the Father and of the
Son and of the Holy Spirit, 20 teaching them to observe all that I have
commanded you. And behold, I am with you always, to the end of the age."
Matthew 28:18-20 (ESV)
A disciple is a follower of Jesus Christ. In keeping with the mandate Jesus gave in the Great Commission, a disciple is someone who has been baptized and is learning to obey everything Jesus taught. In short, a disciple is one who hears and obeys God.
If we're going to see real transformation in our own communities and our global engagement, everybody has to be in the game. Each disciple has gifts and skills that can make a difference when mobilized for the good of others. All of life is their ministry both at a local and global level.
