If I was to think of anyone who I would like to have a mentoring relationship with, it would be John Piper.
A fantasy might be that Piper called me up and said he wanted to be my mentor. He says that I will have opportunity to teach at the church he pastors and as I grow and prove faithful that my responsibilities would increase. If such an opportunity opened up to me, I would drop everything and do whatever Pastor Piper asked of me. I would work very hard to succeed. This would be the opportunity of a lifetime.
Well, the fact is that someone greater than John Piper is here. Maybe you would think of some other over achiever but you get the point. When Jesus offers us relationship with Him through the Holy Spirit, this relationship is "the one thing necessary". No longer does reading books really matter. TV and entertainment seem pretty irrelevant. Being mentored one on one with Jesus, being called to be a disciple of Jesus is the only really important opportunity in life that gives our life purpose. Seeing this relationship with Jesus as a more practical opportunity than if someone with power and position in the world offered you a one on one internship is a proper perspective on what the kingdom actually offers us.
When I remember this living relationship in these terms, I begin to strip down my life and prioritize my listening to Jesus and studying his word. Jesus, what spiritual direction are you giving me today? What skill set are you teaching me in order to be faithful in little so that I can receive greater responsibility in your church and with your people and on your earth? Jesus is the one with power and position in the big picture and He is the one who has the skill and the knowledge to teach us what is really vital in life to true success and true influence.
