When dogs come to the kennel, I don't expect them to be on their best behavior. Perhaps at home they are expected to sit, stay, come, don't jump, etc., but at dog camp, they pretty much may act a bit wild.
Which is fine. Remembering obedience when in a different environment is difficult.
What is in our hearts - to love and be kind to others - is a lot more difficult when push comes to shove, particularly if we are getting shoved a LOT.
We can't do it under our own power. We need to ask for God's strength, patience, and perspective. That's about the only way we have any hope. And when we inevitably make mistakes - snapping, swearing - the Lord is only one who can forgive us completely.
Keep trying - keep praying - keep loving.
