The theme of 1 Timothy is that the gospel leads to practical, visible change in the lives of those who believe it. Paul wrote 1 Timothy in order to advise his young coworker Timothy concerning issues that were arising at the church in Ephesus. Throughout the letter Paul grounds Christian behavior in the gospel. First Timothy is a clear call for the church to live out in tangible ways the ethical implications of the Gospel in unity, order, and sound doctrine.
