What would it look like? 
How would your life be different? Would your exercise prescriptions, as provided you by Him, be different than what you’re doing now? Would your “diet” be different? What would your level of fitness be? Would you be using your time differently? What would be your primary form of exercise? What would your trainer be teaching you?
What would your walk look like?
I’d like to hear what you think on this topic. I’ll share my thoughts later.
This is one subject that has been a pet peeve of mine for a long time. I believe that if we are to be effective ministers of the Word of God that we have to be complete ministers…spiritually, physically, mentally and emotionally. I believe that if any one part is lacking that we lack both individually and corporately. It’s time that the Body of Christ realize that we have to start teaching complete healing, restoration and transformation. When we can do that, we will truly be able to do all things through Christ Who strengthens us.
I think he’d have a whole lot to say about how He’d want to help us be fit emotionally, physically and spiritually. About two months after posting this question I led a retreat for men with this as the theme for the weekend.
