Christians don't exercise enough - Hebrews 5-7

I hate to exercise.   I do it because I have to and because I eat so poorly I would enlarge to the size of a blimp if I didn't.   I ride a bike and swim with pain and eat and ride the Harley for pleasure.   But, at the end of the day it is worth the pain (or, since I jump on the scale every morning ... perhaps at the beginning of the day it is worth the pain).   In Hebrews 5:11-14 we read that the writer of Hebrews wants to be able to talk to his readers about something very deep and for mature believers.   But, in verse 14, he tells them that what he has for them is only for those who are "mature" and have "practiced" (exercised in the old King James Bible) themselves.  Maturity, in his logic, comes from those who exercise.  The verses that they have their "senses" exercised or practiced.   The word "senses" here is the Greek Hexis.  It is that part of the life that is not the mere natural habits but those that are learned through study and knowledge.  What the writer is telling us is that true believers should "exercise" or have their deep habits "practiced" by study of the Person of Christ.   That is the essence of chapter 5-7.   When we learn about Christ and learn how He relates to our life we are "practicing" or "exercising" our deeper "senses" and developing better habits.  In our modern language we are "re-programing" our responses.   We don't have to give into the lusts of the flesh; we are reprograming them through spiritual exercise to become mature and not mere infants in our walk.   Do you exercise enough?   Do you stretch your spiritual muscles with a walk in the Word or a run in righteous behavior or lift spiritual weight?    Go out today and exercise.
