Watch your life and doctrine closely. Persevere in them, because if you do, you will save both yourself and your hearers.
The most import thing about a church are its doctrines. Today people believe to be true simply what they desire to be true. However, the teachings and beliefs of a church demonstrate the value that is placed on God and His Word, not simply what is desirable in our day. The apostle Paul taught that biblical doctrine is a means by which people are saved (1 Timothy 4:16). Sadly, there are many who seem to take an appraoch that says, "doctrine divides." In other words, the result of establishing doctrine in our lives is the division of the church. However, the apostle Paul says that one of the results of closely watching your doctrine is salvation.
