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.
Christianity makes the remarkable claim that God completely pardons sinners solely on the basis of their faith, not as a result of anything they have done to deserve it. But doesn’t God care how a person lives? Two equations help explain Christianity’s most misunderstood truth.
Last time, we considered the ‘almost Christians’ who thought they were on-side with Jesus but found themselves denied entry into heaven because of their lack of repentance and relationship with Him. Perhaps that’s still too vague for some people, though. Is there a way to evaluate what you believe to make sure you’ve actually responded to the heart of Jesus’ message? One of the places to look is at the people who walked away. We often hear about the crowds who gathered to hear Jesus speak. But there were also those who heard His message and turned from it. Rightly understood, Jesus’ teaching invites some and repels others. Consider his encounter with a man who walked away, and evaluate your own faith in light of the exchange.
Last time, we looked at an amazing promise of Scripture from Romans 10:9, “if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.” Having understood that verse, however, it may be a little confusing to read Jesus’ words in Matthew 7:21, “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven.” He pictures people pleading to get into heaven but being denied entrance. They call Jesus “Lord” and can even point to some good works that they have done in Jesus’ name (v. 22), but Jesus casts them out saying that He never knew them (v. 23). It seems that they came close to salvation, but not close enough. What were they missing? They lacked what so many ‘almost Christians’ lack today: repentance and relationship. Let me explain.
When someone begins to understand what the Bible calls “good news,” the first reaction is often hesitation. The message that Jesus bore the consequences of our sins at the cross sounds like good news, but almost too good to be true. Part of the reason is that they don’t hear or fully understand what it means to confess, “Jesus is Lord.”
