If you’ve ever shared doubts with a Christian friend about whether you can know that you’ve received eternal life or will go to heaven one day, it’s likely they’ve read to you 1 John 5:13. That’s the verse which says, “I write these things to you who believe in the name of the Son of God that you may know that you have eternal life.” It’s a great verse of assurance that promises us that we can know that we have eternal life. There’s no need to be left guessing. The promise is made to those who believe in Jesus and it has calmed the fears of countless believers. I think it’s a great verse and it’s not wrong to share it with people who have doubts. The problem is that it can be read and applied too simplistically. That’s because it’s a summary statement that comes at the end of a 5-chapter book that has given a series of tests of true and false faith. And so 1 John 5:13 needs to be understood alongside those other tests. The book of 1 John gives at least four tests, alongside our faith in Jesus, that are given to reassure us of our salvation. Let me share them with you.
