A Greek philospoher called Heraclitus said:
"The soul is dyed the colour of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny — it is the light that guides your way."
The first part of that quotation has been tumbling around the space above my neck for the past few days, so I'm going to explore some of these thoughts over the next few days.
One of the first thoughts that occurred to me was about being "transformed through the renewing of your mind" (Romans 12:2).
The things that spend time in our heads are clearly important - so we must choose wisely what we allow in there!
