The HEART

I preached on the annointing of David, the challenging verse is [1 Samuel16v7]the point being,people judge by outward appearance,but the Lord looks at the heart. seems clear to me, yet to my amazement, a brother started to go on about body piercing and ,ties,etc,mybe i am looking at the scripture wrongly,but it does seem to me, whats most important, is the heart.
