Being like David.

David is portaited in the Jewish and Christian tradition as the king of Israel, the one who is set as an example of a godly ruler.

Yet, when you look at the Bible, David is the one who gets it terribly wrong sometimes. You only need to look at the story of Bathsheba and how David first uses her and then kills her lawful husband Uriah. There's lust here, and murder. He probably broke at least three commandments in this one incident alone, if not all of them.

And yet there is something pure-hearted in David. He really wants to do God's will. He gets it wrong, yes. But he also repents and asks for forgiveness. 

Have mercy on me, O God, according to thy steadfast love;

    according to thy abundant mercy blot out my transgressions.

2 

Wash me thoroughly from my iniquity,

    and cleanse me from my sin!

This story shows that we cannot see the world in a dualist way. There aren't people who are just good and those who are just bad. We all get it wrong. Maybe (hopefully) not so much as David did, but we are not perfect.

What is wonderful is that however wrong we get it, there's always a way back to the Father who never tires of forgiving. How could He, if He loves us with such unending love.

For I am sure that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, nor powers, nor height, nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord. (Romans 8: 38-39)
