David is not a Biblical hero because he slays Goliath. If he is your hero for that you must also include Uriah, Bathsheba, Absolom and the treatment of Saul's descendants into the equation. No, David is not a hero in the standard sense of the word. He is a model though of sticking in–literally hanging in with God through thick and thin–that is the hero part of David. He responds to God. Sometimes he continues digging a hole for himself, but then he comes around. May we come around and stick in there in the same way.
So roll up your sleeves, put your mind in gear, be totally ready to receive the gift that’s coming when Jesus arrives. Don’t lazily slip back into those old grooves of evil, doing just what you feel like doing. You didn’t know any better then; you do now. As obedient children, let yourselves be pulled into a way of life shaped by God’s life, a life energetic and blazing with holiness. God said, “I am holy; you be holy. [1 Peter 1:13-16]
