Philippians 4:8

"What a small little part of a person’s life are his acts and his words! His real life is led in his head, and is known to none but himself. All day long, the mill of his brain is grinding, and his thoughts, not those other things, are his history"

- Mark Twain

It is very important to think about what we have been thinking about. What is on your mind? Paul challenges us to think thoughts that are God honouring and life changing.
