1 Corinthians 9:26-27 (New Century Version)
26 So I do not run without a goal. I fight like a boxer who is hitting something—not just the air.27 I treat my body hard and make it my slave so that I myself will not be disqualified after I have preached to others.
-To get better at our own relationship with God, we have to practice. That is where discipline comes into play.
