I have already posted on this topic in my Blogger blog (check it out if you want by clicking here). However, after having gone through 1 John as a whole (as opposed to just the first chapter and a half, which I did on the previous post in my Blogger account), I thought I would add a few more points to the topic.
The whole purpose of 1 John is stated by the author himself: “These things I have written to you who believe in the name of the Son of God, so that you may know that you have eternal life” (1 Jn. 5:13, NASB). This is why John wrote the epistle, so that his readers might be able to know if they have eternal life.
At a quick glance I have counted about 59 tell-tale signs to one’s Christian identity. Out of the 105 verses in 1 John, about 50 of them contain at least one tell-tale sign. That means that on average John gives us a tell-tale sign every other verse in the epistle. Out of the some-odd 60 tell-tale signs, 22 are negative--they identify people who are not Christians. This means that the majority of the tell-tale signs are positive--they affirm those who truly are followers of Jesus Christ. John seems to be focusing on how to know if someone is a Christian and that, as a result, he or she will also know that they have eternal life. One cannot know for certain if he has eternal life if he does not know if he is a follower of Christ. The Bible is clear that only those who are true believers--true followers of Christ--have eternal life. Since John wants his readers to know that they do have eternal life, he must first help them to see that they are true Christians. Let’s sum up the signs involved in 1 John, shall we?
✴Christian Tell-Tale Signs
•Having fellowship with God (1:6)
•Having fellowship with one another (1:7)
•Walk or abide in the light (1:6, 7; 2:10)
•Daily confess one’s sins (1:9)
•Keep God’s commandments (2:3, 5; 3:24; 5:2, 3)
•Loving one’s brother or loves the brothers (2:10; 3:14; 4:7, 21; 5:1)
•Abides in love (4:16)
•Confesses the Son (2:23; 4:2, 15)
•Abides in the Son and in the Father (2:24; 3:24)
•Practices righteousness (2:29; 3:7, 10)
•Laying down one’s life for the brothers (3:16)
•The Spirit abides in him/her (3:24; 4:13)
•Listens to Christian leaders (4:6)
•Believes that Jesus is the Christ (5:1, 4, 5, 10)
•Loves God (5:2)
•Has the Son of God--Jesus Christ (5:12)
•Does not lead a lifestyle of sin (5:18)
✴Non-Christian Tell-Tale Signs
•Say, “I have no sin” (1:8)
•Say, “I have not sinned” (1:10)
•Does not keep God’s commandments (2:4)
•Hating one’s brother; not loving one’s brother (2:9, 11; 3:10, 14, 15; 4:8, 20)
•Loving the world or anything in the world (2:15)
•Deserting the brothers (2:19)
•Denies the Father and the Son or does not confess the Son (2:22, 23; 4:3)
•Practices sin/lawlessness or lives a lifestyle of sin (3:4, 6, 8, 9, 10)
•Does not listen to Christian leaders (4:6)
•Does not believe in Jesus (5:10)
•Does not have the Son of God (5:12)
It seems to me that John was focused on enabling his readers to best determine their position relative to Christ: those who stood with him versus those who stood against him. Once he established what it means to stand with or against Christ, he could then make the minds of those who are truly with Him to know without a shadow of a doubt that they have eternal life.
Now let me ask you something. After having read this post, do you know for sure if you have eternal life?
