Grace turned outward is more a statement regarding the true nature of grace than anything we do or put on - as if you could receive grace and not give it out. Grace turned outward is part of the definition of grace. It's a sign that one understands the work of grace in their own life. Grace given is grace received. You can't have one without the other.
You don't go out and try to muster up enough grace to share with someone. You merely extend what you have received. If you can't give it, you probably didn't get it, at least you didn't recognize it as grace. Again, turning grace outward is not something that is hard to do. It is the natural outflow of truly understanding and receiving the grace being extended to us by God.
God's grace humbles us; it levels the playing field. We are all equally undeserving. We are all equally needy. So that when we get it, grace changes us.
