Neglect not the gift that is in thee, which was given thee by prophecy, with the laying on of the hands of the presbytery. Meditate upon these things; give thyself wholly to them; that thy profiting may appear to all. Take heed unto thyself, and unto the doctrine; continue in them: for in doing this thou shalt both save thyself, and them that hear thee.” 1 Timothy 4:14-16 (KJV)
Without getting into a speal about the gift given, this verse deals with the idea of teaching doctrine; it is at least one of the things. Is doctrine important in the Christian life? Most certainly. However, I see that there are many younger pastors and preachers who are neglecting to teach the teachings of Scripture to their people; the people they lead.
How important is doctrine? “…For in doing this thou shalt both save thyself, and them that hear thee.” It is very important for the sanctification of ourselves, and the people.
