The eternal security of our salvation is a hotly debated topic amongst Christians today, Bible teacher and broadcaster Brian Johnston examines what the Bible has to say about whether it is possible to 'fall away' and how God wants us to be sure that we are saved. He explains how law and grace are two different freedoms, whether it's possible to be a 'carnal Christian', whether it's a case of "no holiness, no heaven", if good works are required for salvation, is it possible to fall away and shows how an understanding of the 'three tenses of salvation" can help give us assurance that we are saved.
