Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up. Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers. - Galatians 6:9-10
Kindness doesn't come easily to everyone. We're easily offended, and always want to be right. But we're called to do good. To ALL people. And to keep doing this. Even when we in a bad mood, when we're hurting, and when we really just don't feel like it. Don't give up on doing good. Show the world the love of God through your kindness!
