Christ's Atonement --- The Only Way Out
If God does not take sin seriously then our good works may be able to pay for its penalty. But, if He does it take it seriously (and He does!) then no amount of good works can pay for the penalty of our sins and therefore save us.
We will all have to face a God who takes sin very, very, very seriously. A God who declared that the "wages of sin is death" (Rom. 6:23).
Only an eternal death can satisfy an absolutely holy and eternal God who takes sin very seriously. It's eternal death or nothing for us. It really looks like it's game over for us. But hope springs eternal when the Lord Jesus Christ came and died FOR us and AS us. His death on the cross for us has an eternal value because He who died on the cross was Himself eternal.
Now, all we have to do is to appropriate His death on the cross for us by relying on it. It was provisionally for us. Now, we must embrace it and cling to it for dear life.
And God who sees you making use of Christ's death on the cross will declare your sins as forever paid and cancelled.
