Know Sanity
There are some times when we quietly stuff our emotions and hold back our true words in situations when we should feel freely and speak to help that we harden out hearts against truth.
We've been recently trained in our societies to freely feel, so now realize that your speech is powerful for righteousness when it is true, except the hearer disregard God's truth that you speak, and powerful for evil when it is false, except the hearer disregard your falsehood.
Feel, seek, see, do, speak God's Truth, and know sanity.
