overcoming impurity with charity

Luke 11:41 "But give that which is within as charity, and then all things are clean for you."

We underestimate the power of serving others. Sometimes we think, “I can’t serve others because I am so jacked up.” But in actuality it could be that serving others could help us not be so jacked up. I think that selfishness is more ugly than any of us can imagine contaminating us from the inside out. I also think that selflessness is more beautiful than any of us can imagine purifying us simultaneously from the outside-in and the inside-out.

How can you "give that which is within as charity" today?
