1 John 2:18-27 - Departure Of The False Teachers
18 Dear children, it is [now] the last hour [i.e., the final period of God's dealing with people on earth], and since you have heard that an antichrist [i.e., a person who is against Christ] is coming, even now [you should be aware that] many antichrists have [already] come. This is [one way] we know that this is the last hour. 19 These antichrists left our group [i.e., withdrew their fellowship from us], but they were not [really a part] of us, for if they had been, they would have continued [to participate] with us. But, by their leaving us, it proved that none of them were [really] a part of our group [after all].
20 But, you people have a "special gift" from the Holy One [Note: The Greek word for "special gift" is "charisma" and probably refers to the Holy Spirit (See Acts 2:38); "Holy One" probably refers to Jesus, (See Acts 2:27; 3:14)], and all of you know [the truth]. 21 I did not write to you people because you are ignorant of the truth [about these matters], but because you do know it, and because nothing false belongs to the true teaching. 22 Who is the liar? It is the person who denies that Jesus [truly] is the Christ [i.e., God's specially chosen One]. This person is the antichrist [See verse 18]; he is the one who denies [the truth about] the Father and the Son. 23 Every person who denies [the truth about] the Son [See 4:2-3], does not have the Father [living in his heart]; but, the person who confesses [the truth about] the Son has the Father [living in his heart] also.
24 You people should continue [to practice] what you heard from the beginning [i.e., to love one another, See verses 7-11]. If you do, then you also will continue in [fellowship with] the Son, and with the Father. 25 And this is the promise which Christ [or, "God"] has given to us: [It is] never ending life. [Note: This passage may mean that God promised us "the Eternal Life," that is, Christ, See John 3:16]. 26 I have written these things to you people concerning those who are trying to lead you astray [from the truth].
27 And this is important to you: The "special gift," which you received from God [See verse 20], continues to live in your hearts, [so that] you do not need anyone to teach you [anything different]. But, since this same "special gift" teaches you concerning everything that is true, and [what it teaches] is not false, you should continue to live in [fellowship with] Christ.
