1Tm4

Whatever you are committed to and practice, that is what you value. The question is: Are we committed to and practicing the right things? Paul encouraged Timothy to discipline himself to be godly. He told him to persevere in this discipline because it matters forever. He encouraged Timothy to set an example for other believers in speech, conduct, faith, love and purity. 

If every believer was as disciplined as you, how well would Christ be being represented in our culture? Your life as a christian matters and each of us should be working hard to become a better representation of Jesus. We should "pay close attention to our life and our teaching" because it does have an effect on us and on others.

We all have disciplines. We all are getting better at something. Make sure those things are the things that truly count.
