Avoiding the toll

At Voice of Vision J.D. Hatfield encourages Christians to practice real repentance and turn from sin:

In 1 Corinthians 10:1-10 Paul uses the children of Israel in the wilderness as an object lesson about presuming upon the grace of God. Although they had escaped the bondage of Egypt, and had known of God’s grace and had experienced it (vs.1-4), nevertheless, many were still in bondage to sin, and they were judged (vs.5).

Could there maybe be a lesson there for Christians today?
