How much does doctrine direct your life?

How much does doctrine direct your life?
Titus 2
Have you ever thought of that question?
Here’s another:
Is doctrine just about what you believe or about what you become?
Titus teach doctrine:
The Word of God, v5
God being Saviour, v10
The grace of God, v11
The return of Jesus Christ, v13
Redemption, v14
And why teach these doctrines?
So that whether you are an older man or woman, a younger woman or man or a worker you become nicer people.
Doctrine should direct you to being a better person.
