There's a missing key in Christianity today. It's a critical one, and its absence has led to weak believers, ineffective churches, and a decaying culture. That missing key is discipleship. This Bible study calls believers and churches back to our primary responsibility-to be and make disciples. Through six sessions, Dr. Tony Evans shows what it means to be a kingdom disciple-a believer in Christ who takes part in the spiritual-development process of progressively learning how to live all of life under the lordship of Jesus Christ. He also demonstrates what discipleship looks like for individuals, families, churches, and communities. Only when we take this assignment seriously will the world see heaven at work on earth.
