Now in a large house there are not only gold and silver bowls, but also those of wood and clay, some for honorable use, some for dishonorable.So if anyone purifies himself from anything dishonorable, he will be a special instrument, set apart, useful to the Master, prepared for every good work. (2Tim 2:20-21, HCSB)
You know that in a race all the runners run, but only one gets the prize. So run to win! All those who compete in the games use self-control so they can win a crown. That crown is an earthly thing that lasts only a short time, but our crown will never be destroyed. So I do not run without a goal. I fight like a boxer who is hitting something—not just the air. I treat my body hard and make it my slave so that I myself will not be disqualified after I have preached to others. 1 Corinthians 9:24-27
