I remember a conversation during college in which a friend confessed to me that he did not think it was necessary, or even possible, for a believer to gain assurance of their salvation. I was surprised by his comments, especially because we were attending a Christian college that emphasized all the biblical truths related to assurance of salvation: election, grace, faith, repentance, substitutionary atonement, the fully deity and humanity of Christ, and eternal security.

As it turns out, this was not an isolated incident. Over the past several years as I’ve wrestled personally with the issue of assurance and had opportunity to speak to others about it, I’ve found that many Christians do not rightly understand the biblical basis or importance of this doctrine. Assurance is essential to genuine Christianity and central to the New Testament’s theological framework, yet plenty of Christians are content to walk through life without the sure knowledge that they belong to Christ. There are, of course, those who claim assurance who have no right to do so; but it seems that there are an equal number of professing Christians who have either resigned to the fact they will never have assurance or that they don’t really need it.

What is assurance?

When I use the phrase “assurance of salvation” I am referring to a professing Christian’s confidence that he is, through the gospel, presently in right standing with God and will, upon his death or at the return of Christ, enter into eternal life and be delivered from the penalty of eternal condemnation. Assurance is the present intellectual and heart-felt conviction that I am, at this moment and for eternity, at peace with the living God through Jesus Christ.
