Just like Saul before him, David has fallen as the shepherd-king and done evil in the eyes of the LORD. His house will now experience curse rather than blessing- the people have fallen with their king.
Sin makes us see everything wrongly- God ourselves and others. And we do great harm to each other with destructive consequences. In Jesus we see the good shepherd- king who shows us grace and forgiveness.
When do you trust your own insight? Admit the damage our sin causes and live in the forgiveness and care of the good shepherd. Is there someone you need to ask for forgiveness from?
See how good God has been to you and how much he has blessed you in Jesus. Who do you need to be accountable to? What friendships can you be cultivating to keep you accountable?
