How do you understand the enormity of God's grace?

Joel Beeke shares in this video that there was a medieval theologian who wrote a book about the Atonement that explains how great sin is and how great grace is. T see the enormity of grace, you must see the enormity of your sin.

As pastors, we need to preach the enormity of sin so that our congregation and run to Christ for the forgiveness of their sins. Both issues deserve equal attention. For instance, pastors should not overly emphasize the goodness and grace of God while neglecting to preach about the sinfulness of sin. 

Romans 6:1-4 (NKJV) – “What shall we say then? Shall we continue in sin that grace may abound? Certainly not! How shall we who died to sin live any longer in it? Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death? Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.”

You know, there was a medieval theologian by the name of Anselm, and he wrote actually a very good book on the atonement. And it's a dialogue, really. It's called Why God Man, Why God Became Man. And Anselm, It's a dialogue with a man named bozo which is a beginning Christian He has a lot to learn and his name very name Sounds like that doesn't Bozo and then some is trying to teach bozo about how bad sin is How great grace is and bozo can't seem to get either end of that equation? And finally Because bozo doesn't really feel the necessity of the atonement, the necessity of the blood of Christ.

Anselm looks at bozo in frustration and says, Bozo, your problem with understanding the enormity of grace and the necessity of bloody atonement alone. Your problem is that you don't understand the enormity of your sin. And so as pastors, we need to preach the enormity of sin so we get people, by the grace of God, to thoroughly repent, but also to run to Christ with all their sins and all their need.
