"Imagine going for a run while eating a box of Twinkies. Besides being self-defeating and side ache-inducing, it would also be near impossible–you would have to stop running in order to eat the Twinkies.
In the same way, you have to stop loving and pursuing Christ in order to sin. When you are pursuing love, running toward Christ, you do not have opportunity to wonder, Am I doing this right? or Did I serve enough this week? When you are running toward Christ, you are freed up to serve, love and give thanks without guilt, worry or fear. as long as you are running, you are safe.
But running is exhausting–if, that is, we are running from sin or guilt, out of fear. (Or if we haven’t run in a while.) However, if we train ourselves to run toward our Refuge, toward Love, we are free–just as we are called to be."
