I was reading a book today, called "Covenant and Kingdom" by Mike Breen, and was struck by this quote:
"The process of discipleship is ... adopting another person into our family. We introduce people to our Father and invite them into a relationship with him. We invite them into a Covenant relationship of friendship with us and challenge them to do the works of the Kingdom. They discover that the God who has become their Father is also the King of the universe, and that their challenge, like ours, is to represent him."
Hmm... It's all about relationship. Jesus invited me into relationship with him, and as a member of his family I represent him and our Father wherever I go. And as he shapes me into his image, I will more naturally join him in his Kingdom plans, inviting others that I know to join in also.
