I've been thinking about the subject of the Christian's assurance of salvation. To put my cards on the table, I don't struggle with assurance of salvation personally at all. I'm far more inclined toward the "wider mercy" view of God's love than I am toward any apprehensions about whether I am among the elect. My struggles are over entirely different subjects: Does God exist? How can I face death without losing my sanity? Check in with me on those topics and I'll buy your joe.

I'm interested because I spend a significant amount of time counseling students and adults on the subject of assurance. These are people who are unsure whether or not they are Christians at all. Some feel they never were, but most feel they've somehow started, and now failed, in their Christian faith. I rarely have anyone come to me doubting that God exists or questioning whether the Bible is true- both questions I would expect to hear frequently given the student population that I minister to at a boarding school. Instead of these fundamental questions, I continually have a conversation something like this:

"I used to think I was a was Christian, but I don't think I am any more."

"What has convinced you that you're not a Christian?"

"I don't live like a Christian. I do a lot of things that I know Christians don't do. I rededicate my life to Christ all the time, but I just go right back to the same old things, and I don't see how a Christian would be so hypocritical. I'm lazy, and I really don't live the Christian life."

See the remainder of the article here.  He brings up a good point in this article, a point that is important for Christians to engage.  The best book I know of for helping Christians think through issues of justification, sanctification, and assurance is The Race Set Before Us.

This is a great book and is well worth the price.
