1 John 4:8 But anyone who does not love does not know God, for God is love. 1 Corinthians 13:4-7 Love is patient and kind. Love is not jealous or boastful or proud 5 or rude. It does not demand its own way. It is not irritable, and it keeps no record of being wronged. 6 It does not rejoice about injustice but rejoices whenever the truth wins out. 7 Love never gives up, never loses faith, is always hopeful, and endures through every circumstance.
When we find ourselves speaking outside the realms of love, we need to check our thoughts and our heart. Our mouths are a gauge for where our heart is at the moment. When love is in our hearts, love comes out of our mouths. When God is in our hearts love comes our of our mouth. Our words are more important than we can even think to imagine.
