In our OT passage we see the consequences of wrong actions, even with right motive. King David did not follow God's instructions on handling the ark - and though it doesn't seem to have been deliberate, it was certainly careless. We can never be careless about the potential for sin!
The story illustrates just how prone we are to sin. We sin when we accidentally do something wrong. We sin when we don't bother to find out what God thinks about an action. We sin when we do the wrong thing for the right reason. We sin when we do the right thing for the wrong reason. We sin when we do the wrong thing for the wrong reason. We sin when we don't do the right thing.
We are so desperately in need of a Saviour. Thankfully, as our NT passage shows us, God is passionate about each and every one of us acknowledging our sinfulness and our need of a Saviour, and He rejoices over every sinner that repents of their sin and relies on Him for forgiveness and reconciliation!
