There are some Christians who treat the grace and mercy of God as if they are a "get out of jail free card"; meaning that we can do whatever we want without any consequences. It is certainly true that Jesus' sacrifice has rescued us from the ultimate penalty of sin, but as we see in this expository sermon from Hebrews 2:1-4, Christians must beware of the danger of drifting and the consequences that can follow. Sermon begins at 21:10.
