1 Timothy 4:15-16

Take pains with these things; be absorbed in them, so that everyone will see your progress.  Be conscientious about how you live and what you teach. Persevere in this, because by doing so you will save both yourself and those who listen to you.

Paul is charging Timothy with living a life committed to living out what he teaches. The Lord wants our lives to reflect sound teaching, and He wants our lives to become evidence of His redemptive plan and part of His gospel message to everyone. Our words are able to speak the truth, but when our lives line up with the truth we speak grace floods from us and assaults the shroud and deception of this world. When we are obedient to the Lord His message of truth and hope, the gospel, shines from us. Obey the gospel and become a part of His message of hope and salvation!
