We have a BIG problem.
Sin has disconnected us from God. Here we are, like we are floating through space, cut off from our life supply.
So you might ask, "Well, why can't God just make all that sin disappear and hook us back up again?"
Because it's not that simple. Here's why...
The trouble is, sin ruins everything.
Just think of all the terrible things in the world. That's what sin does. My sin, your sin, added to all the sin in the world ruined everything. Sin is a terrible, terrible thing because sin is what brought death into the world.
And a price has to be paid for all that terribleness.
Well, suppose one day your brother just up and smacks you a good one. And then your dad says to him, Oh, thats okay, we'll just forget about it - just dont do it again... oh, and if you do, well, thats okay too.
What??!! That's not right!
Just forget about it?! Like it never happened??!! No! That's not fair! He has to be punished! He should have to go to his room, or not get any dinner, or something! You can't just let him get away with it!
And you are right!
And that's how it is with God. Every time we sin, someone gets hurt. It may not always seem like it at the time, but someone does. God always does. God can't just say, Oh, thats okay - just dont do it again... oh, and if you do, well, thats okay too.
That wouldn't be right!
And God is perfect in every way. God could never do what isn't right. That's just not who God is!
And thats the problem for us.
We are all guilty.
God can't just make our sin disappear. God can't pretend it never happened. In order to make things right, a price for our sin has to be paid.
