A disciple is someone who is a lifelong learner of Jesus. And then a disciple disciples others.
It doesn’t mean a program. It doesn’t always take place in a classroom. It doesn’t have to be a scheduled meeting between people with a particular study to go through. So often, and sometimes the best times, discipleship happens organically. It happens as we are walking through life with people, investing in their life, hearing their story and caring enough to open our life to them. That is what we are called to if we call ourselves followers of Jesus.
