Have you ever said something and regretted it after you had some time to reflect on it? I can recall plenty of times when this was the case for me. When I was younger, I was really outspoken and just spoke the things that came to mind. At that time I really did not understand that I should not speak all the thoughts in my head but listen more to understand others. The Bible confirms this in Proverbs 21:23 "Whoso keepeth his mouth and his tongue keepeth his soul from troubles."
Now you may be wondering, what is the harm of speaking all of the thoughts that come to mind?
Well, let's look at Matthew 15:18-20 where Jesus explains that it is not unclean hands that defile a man. Actually, Jesus says in verse 18 "But those things which proceed out of the mouth come forth from the heart; and they defile the man." Basically, the harm of speaking all of our thoughts really shows us what is in our hearts. This verse really got me thinking back over some of my recent conversations. I even began to dissect the words spoken by me because I wondered if I guarded my tongue and heart or allowed them to run wild.
After my examination I asked God, so how can my heart be healed if I am still saying things that are defiling me? That is when the Holy Spirit reminded me of Psalm 51:10 which says "Create in me a clean heart, O God; and renew a right spirit within me." By allowing God to clean our hearts, we will speak in a way that will not cause those troubles mentioned in Proverbs 21:23. So I implore you to examine the words that come from your mouth because it will show you what are the matters of your heart!
