Ephesians Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice. Be kind to one another, tender-hearted, forgiving each other, just as God in Christ also has forgiven you.
You will never truly understand the struggles of another person. Remember to realize how hard your own struggles are for you. The other guy feels the same way. We are all trying to make our way in this world so make it easy on everyone and don't judge.
