1 John 2
1. He comforts them against the sins of infirmity.
3. Rightly to know God is to keep his commandments;
9. to love our brothers;
15. and not to love the world.
18. We must beware of antichrists;
20. from whose deceits the godly are safe, preserved by perseverance in faith, and holiness of life.














If anyone says
This phrase introduces a hypothetical scenario that is universally applicable. The Greek word for "says" is "λέγῃ" (legei), which implies a verbal profession or claim. In the context of the early church, many individuals professed faith in Christ, but John emphasizes that mere words are insufficient without corresponding actions. This sets the stage for a discussion on the authenticity of one's faith.

I know Him
The Greek word for "know" is "γινώσκω" (ginōskō), which implies an intimate, experiential knowledge rather than mere intellectual assent. In the Jewish context, to "know" God was to have a covenant relationship with Him, akin to the deep, personal knowledge shared between close friends or family. This phrase challenges believers to examine whether their relationship with God is genuine and transformative.

but does not keep
The word "keep" is translated from the Greek "τηρῇ" (tērei), which means to guard, observe, or maintain. It suggests a continuous, diligent effort to adhere to God's commandments. In the historical context of the early church, this was a call to live out one's faith through obedience, reflecting a life transformed by the Holy Spirit.

His commandments
The term "commandments" refers to the moral and ethical teachings of Jesus, rooted in the Old Testament law but fulfilled and expanded in the New Testament. The Greek word "ἐντολάς" (entolas) indicates directives that are not burdensome but are expressions of God's will for His people. This highlights the importance of aligning one's life with the teachings of Christ as evidence of true discipleship.

he is a liar
The Greek word for "liar" is "ψεύστης" (pseustēs), which denotes someone who is deceitful or false. In the biblical context, lying is not just about falsehood in speech but also about living a life that contradicts one's professed beliefs. This stark statement serves as a warning against hypocrisy and self-deception.

and the truth is not in him
"Truth" in Greek is "ἀλήθεια" (alētheia), representing not only factual accuracy but also sincerity and integrity. In Johannine theology, truth is closely associated with the character of God and the revelation of Jesus Christ. To say that the truth is not in someone is to assert that their life lacks the genuine presence and influence of God's truth, which should be evident in the life of a believer.

Verse 4. - The participial substantive ὁ λέγων now takes the place of ἐάν with the subjunctive, but the two are equivalent (cf. 1 John 1:6, which is almost exactly parallel to this, and shows what "knowing him" really is, viz. having fellowship with him, just as not keeping his commandments is the same as walking in darkness). St. John says, μὴ τηρῶν, not, οὐ τηρῶν, the case being hypothetical - if there be such a man, he is a liar, and has no idea of truth (see on 1 John 1:8). He must have lost the very power of recognizing truth to maintain that he knows Christ, when he habitually transgresses his commands. It is no great thing, as Bode says, to know as the devils do, who "believe and tremble."
