On this blog I have wrestled, alongside some of you, with the following question: “If I have truly been justified by God, is it possible for me to lose this gift, such that unless I repent and seek God’s forgiveness and grace—literally become re-justified—I will go to hell?” Wesleyan Christians believe the answer is “yes.” We believe backsliding (for that is what we call it when it happens) is a real and present danger, even though we also preach assurance: for those who are (presently) justified, they can know they’re justified through the witness of the Holy Spirit within them. (See Romans 8:12-17 for one classic proof-text.)
Indeed, in a post a couple of months ago on infant baptism, I said that only a belief in the reality of backsliding can sustain the sacramental view of baptism that many Protestants, including Methodists, hold.
As I’ve said before, the issue of backsliding is purely a secondary doctrine: Whether we lose our justification through persistent, unrepentant sinfulness, or persistent, unrepentant sinfulness proves that we never had it to begin with, the result is the same. Consequently, all of us—believers in backsliding or in eternal security—need to seek assurance.
For this reason, I fully endorse this video from John Piper. Reflecting on the Romans 8 passage, he offers two reasons for assurance: hatred of our sin and childlike dependence on our heavenly Father. (This clip also demonstrates in small measure why Piper is among his generation’s most gifted preachers! What a show-off! 😉 )
