1 Peter 1:13-15 (ESV)
Therefore, preparing your minds for action, and being sober-minded, set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ.  As obedient children, do not be conformed to the passions of your former ignorance,  but as he who called you is holy, you also be holy in all your conduct,
The Greek Reads gird up the loins of your mind for action. The image is a jock strap, a rather vulgar metaphor by today’s standards. In Greek culture it is my understanding anyway, most sports were played in the nude. This is really a reference to getting ready for battle. Gird up your loins. Gird up the loins of your mind. The Christian faith is an intellectual faith. It isn’t that intellectualism is the sum total of faith, but Christianity does not ask you to check your brains at the door. Rather it invites you to use your intellect, it invites you to study, it invites you to debate. It asks you to use your head, and not the one normally reserved for the jock strap. Rather it asks you to be sober minded about those things, not being conformed to the passions of your former ignorance.
Be sober-minded, that is have a clear head, count the cost, weigh it all out, and with that sober mind set you hope fully on the grace that will be brought to you at the revelation of Jesus Christ. This is the opposite of what happens in so many churches on Sunday morning today. Emotionalism rules the day. People go to church to be “up-lifted” by which they usually mean they want some sort of ecstatic experience. They want an emotional high. Much of the Music penned for worship these days, passing for Christian Music, is about this, creating an emotional high, and often a rather superficial high. And it is this that is meant to be the tool for “conversion.” But this doesn’t contribute very well to maturity. Perhaps that is why you don’t see very much gray hair in those congregations.
I hear it, mostly from gray headed people themselves, that there is too much gray hair in our congregations. I’m not all that sure what they are talking about as I’m kind of tied down to one congregation these days on Sunday morning, and I see a wonderful mix of the generations there. But I would think there has to be something to a congregation with a lot of gray hair. If I were looking for a congregation as a young person myself, I think I might look for a congregation with an abundance of gray hair. We are to grow in Christ and mature, and Christianity puts a big emphasis on respecting our elders. I don’t know how much I could learn about maturing from another 30 something, or someone younger than that. I don’t know how much my children could learn from them either. But to have an abundance of gray hairs for them to learn from, now that is a blessing. At least, I thought it was a blessing when I was growing up. My dad used to farm me out to the older people in the congregation to do odd jobs for them etc. I learned a lot from them. Still see them now and again. An old man with gray hair can do more to keep your kids off of drugs, and from knocking up his girlfriend then any youth group, believe me. You might not think they have that much in common, well they have more than you would no, and a lot more wisdom than the 30 something soccer coach.
