When a person walks away from the faith, what happened? Are they Christians gone astray? Have they somehow managed to lose their salvation? Were they ever truly saved? The author discusses the issue of whether a saved person can be lost again, and then examines each of the major biblical passages describing personal apostasy. The case for eternal security is presented, including a thorough discussion of personal apostasy, with each of the major New Testament passages on the subject treated in detail, including: 2 Peter 2:1-22; Hebrews 3:1-14; 6:4-12; 10:26-31; and 12:14-29, and 1 John 1:1-3:12.
