The community of believers, being fashioned together in Christ, is called to be faithful and not to turn away. The Israelites in the desert hardened their hearts when the going got tough. They complained against God and longed to return to the security of Egypt, even though there they had been slaves. The author warns the followers of Christ not to rebel as they rebelled, for if God cut off those he brought out of Egypt with mighty miracles, he can also cut off those who turn back from following Christ if they also rebel and complain.
Sermon: Hebrews 3 7-19
