Germs are funny things. Once they are out there, they continue to multiply and spread and are seemingly everywhere. And once they’re out there, they are seemingly impossible to get rid of. Which is why all the cleaning bottles tell us they get rid of 99.99% of germs. But .01% remain. And you know what that .01% will do? They will multiply and spread!
I want you to imagine that you could be in a perfectly clean room. It’s spotless, not even .01% of germs live in here. If you’re a germaphobe, this is your paradise. This is the one room where you can relax and know that all is right in the world. If you were ever a fan of the TV show Monk, then you remember his obsession with cleanliness.
But let’s say you leave the room, even just for a minute. When you return to this room, you know what you bring with you? Germs! Good luck getting it clean again, since all the cleaners only kill 99.99% of germs. Many attempts could be made to make the room clean again, but at the rate that germs reproduce it would not be possible. The solution would be to create a new clean room.
No analogy is perfect, but this is what God did in Jesus Christ. The sacrificial system was not working and so God made a New Covenant. I don't want you to assume God is a giant germaphobe with a bottle of spray cleaner in hand, but He does desire us to be clean. He uses to word holy.
But now he has reconciled you by Christ’s physical body through death to present you holy in his sight, without blemish and free from accusation— ~Colossians 1:22
