As I have gotten older, I've realized this truth...The wiser you become, the less offended you get at things. I use to get offended all the time by Ken. If he said something or did something I didn't like, I would get all offended and pout, get angry, and give him the silent treatment. It's pretty ugly now looking back on that behavior.
When we get older, we are told to put away childish things and pouting and stewing are childish.
People have a right to their opinions or can act stupid if they want. If we get offended by that, we are only thinking about ourselves and our feelings. Let people be who they are, think what they want, say what they want, and act like they want. You are not responsible for them.
You are only responsible for your actions and responding in anger, pouting, and with the silent treatment isn't a mature way to act. If people disagree with you in your faith, politics, beliefs, or your convictions, give them grace to believe as they want and love them anyway.
That is what life is about, remember, loving God and loving others. Learn to dialogue with them in a loving way realizing that the relationship is way more important than being right.
Be completely humble and gentle; be patient, bearing with one another in love.
