Being a follower of Jesus, a disciple, is not the easiest way through life. Discipleship is uncompromising devotion, a struggle that costs all effort - and is worth it.
The author places the biblical statements clearly and without compromise in the current context of our everyday lives.
The reign of Jesus should become concrete. This is ultimately what distinguishes discipleship. Anyone who is available to God in this way lives to his glory and also becomes a blessing to other people.
