Jude 1:11 Woe to them! For they have gone in the way of Cain ...
What was the way of Cain? Among other things, Cain, as we read in the book of Genesis, was a man who did not have an adequate sense of sin. Hence, he was a man who did not see his need of atonement. Instead of offering a sacrifice, which was a picture of the coming sacrifice of the Savior, the Lord Jesus Christ, he, instead, offered the work of his hands from the ground; he did not offer an atoning sacrifice at all.
There are people who go about this moral universe who resist the nagging conviction that they are sinners, worthy of judgment, unable to save themselves. Hence, they are a people who see no need of what the Lord Jesus Christ did for them on the cross. Instead, they rely on what they are and what they have accomplished for salvation.
Woe to them! For they have gone in the way of Cain!
My friend, don't you sense the sad fact that you are a sinner worthy of judgment? A sinner who is totally helpless in saving your self? Have you not realized your need of the Savior and what He did on the cross for your sins?
Are you one of the many who tread on Cain's Street?
