Our Thoughts

During an online devotional last week, the leader said she had read that we all think 50,000 thoughts a day. More than 50% of them are negative, and at least 90% of them are thoughts we had the day before. 

That phrase stopped me in my tracks.  Really?  90% of our thoughts today are the same as the thoughts we had yesterday?  I just picture rerun after rerun of thoughts.  And if more than half of them are negative, what does that say about our what is going on in our minds.

If we want to grow in Christ today, it seems to me that our thoughts would be a place to start. What thoughts of ours, that echo through our days, reflect hatred, judgment, or grace-less-ness? How can we change them?
