This important passage from Ephesians admonishes us to change our lives in keeping with our vocation as Christians. It is something we all need reminding of frequently and it is something we need to keep front and center in our prayer intentions--that we respond to the grace we are given to live out our lives in Christ.
Therefore each of you must put off falsehood and speak truthfully to your neighbor, for we are all members of one body. “In your anger do not sin”: Do not let the sun go down while you are still angry, and do not give the devil a foothold. Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen. Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice. Be kind and compassionate to one another, forgiving each other, just as in Christ God forgave you.
Ephesians 4:25-27, 29, 31-32
