1 Corinthians 9:27 No, I strike a blow to my body and make it my slave so that after I have preached to others, I myself will not be disqualified for the prize.
How much do you actually try and keep yourself from doing things? Are you like a shadow boxer who is making all the right moves but not actually hitting the mark, or do you go into a fight for real?
We have to be honest about what we can do but also honest about when we are giving in and going with the flow.
If it means taking a hit so you will remember what you have done wrong, then just maybe that is what we need to do!
