1 John 2:18-19: God’s Good Purging

1 John 2:18-19: Children, it is the last hour, and as you have heard that antichrist is coming, so now many antichrists have come. Therefore we know that it is the last hour. They went out from us, but they were not of us; for if they had been of us, they would have continued with us. But they went out, that it might become plain that they all are not of us. [1]

 Some words can only be described as “theological grenades”: words that spark a series of often conflicting opinions. One of those words is “antichrist” and it is in verse 18. Why does John mention one antichrist then several in the same verse? John is helping us see that the antichrist is someone who denies Jesus Christ’s deity and work. [2] Verse 19 reveals these antichrists have come from the church. [3] This does not mean that the church is erroneous, but that there are people who are not saved in church. [4] The reality that unbelievers are in church, and they will leave and spread their sin should not alarm true Christians. [5] Rather, God’s purging His church calls real believers to thank God for His work in giving them salvation and perseverance, and to guard the church. [6]

 If John called his readers to rejoice in Christ’s salvation and to vigilance over doctrine years ago, how much more so should we? [7] We fail to love when we let someone live in improper doctrine. [8] While this is not ground for theological bullying, we cannot be cowards either. [9] One of the most loving things we can do is joyfully tell others about their need for Christ, as someone else lovingly told us.
