Keep thy heart with all diligence; for out of it are the issues of life. Proverbs 4:23 KJV
What you hide in your heart is what will come out of your mouth for evil or for good.
Thy word have I hid in mine heart, that I might not sin against thee. Psalms 119:11 KJV
My heart is set to please the Lord with my words. How about you?
