“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.”
1 Timothy 4.16
It appears that Timothy was easily distracted from his main task. Paul calls him to concentrate on the gospel. Only the gospel saves.
We must practice what we preach. We must also preach what we practice, for people are saved by the words of the message of Christ, Acts 11.14.
