In order for Adam and Eve to properly teach their sons about sin, they had to point to themselves. Where else were they going to look? It was Adam and Eve that fell and brought sin into the world, and this they couldn’t hide from their boys. There was no way they could point the finger at anyone else, because there was no one else there to point the finger at.
This is a sobering, yet essential example for believing parents. It is our duty to make sure we model repentance to our children. It is a major part of loving them rightly, bringing them up in the nurture and admonition of the Lord, and teaching them about the grace of the Gospel of Jesus Christ.
When we as parents fail to do this, we are always looking to point the finger at someone else. The more our children see this, the more it becomes the standard in their own lives. If any parent had a desire to hide the truth of sin from their children, it was the first Adam, the perfect, created man who walked in fellowship with God in the garden. I’m sure it wasn’t an easy thing to teach his children about sin, but this he did, and this we must. For if our children understand nothing about guilt, they will never understand grace and repentance. They will avoid repentance because they will avoid their guilt. And God never forgives those who come to him with excuses.
