Paul concludes his letter to his young protege with some closing teaching and advice. The famous "the love of money is the root of all evil" (10) reminds us that having things is not the problem, it is when our things have us that we run into difficulty. Verses 3-10 is sound teaching on the importance of the teaching ministry in the church and how easy it is to stray into things that are not harmful.
Persue righteousness godliness, faith, love, endurance, gentleness -- fight the good fight of the faith (11/12) is Paul's advice to his younger colleague. I used to have a poster that was a communion table laden with a broken loaf of bread and a full chalice of wine. The caption read "Jesus of Nazareth invites you to a banquet held in his honor." This was followed by the middle of verse 12 "take hold of the eternal life to which you were called!"
His final note is to the "rich". I preached on this passage last Sunday.
