I have been leading a study of the first Epistle of John for a few months at my church. We meet each Saturday morning for an hour and a half. I am considering posting the materials I have developed for those studies here to see if there is any interest. the material here will have to be divided up into much smaller chunks for this format. Let me know what you think.
Introduction:
I want to start with two verses from the very end of this epistle to set the tone for what we are about to begin.
1 John 5:13 ESV
(13) 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.
“If the new birth is the root, a changed life is the fruit.” Steve Lawson
Remember these verses from Matthew:
Matthew 7:17-20 ESV
(17) So, every healthy tree bears good fruit, but the diseased tree bears bad fruit.
(18) A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit.
(19) Every tree that does not bear good fruit is cut down and thrown into the fire.
(20) Thus you will recognize them by their fruits.
Matthew 7:21 ESV
(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.)
So, with all that in mind, let us consider also that God wants us to know and fully understand both his word and his son.
1 John 5:20 ESV
(20) And we know that the Son of God has come and has given us understanding, so that we may know him who is true; and we are in him who is true, in his Son Jesus Christ. He is the true God and eternal life.
The word know appears 38 times in the book of 1 John (in the ESV). Knowing that we are saved and having an assurance of that salvation is very important to God.
Take some time on your own to search out each of the instances, underline it (if you want to), and think about what it means in that context.
Let’s begin this study of John’s Epistles with an understanding of the world in which they were written, the people to whom they were written, and the purpose for their writing. To begin with, let’s read the first short chapter.
Verse(s) considered along with Observations & Expositions:
1 John 1:1-10 ESV
(1) That which was from the beginning, which we have heard, which we have seen with our eyes, which we looked upon and have touched with our hands, concerning the word of life—
(2) the life was made manifest, and we have seen it, and testify to it and proclaim to you the eternal life, which was with the Father and was made manifest to us—
(3) that which we have seen and heard we proclaim also to you, so that you too may have fellowship with us; and indeed our fellowship is with the Father and with his Son Jesus Christ.
(4) And we are writing these things so that our joy may be complete.
(5) This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all.
(6) If we say we have fellowship with him while we walk in darkness, we lie and do not practice the truth.
(7) But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin.
(8) If we say we have no sin, we deceive ourselves, and the truth is not in us.
(9) If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
(10) If we say we have not sinned, we make him a liar, and his word is not in us.
The author of this epistle is the Apostle John. There have been challenges to that idea, but the evidence supporting that conclusion is pretty overwhelming. Only two epistles in the New Testament do not directly name their authors. This is one, and the other is Hebrews. The similarities in writing style to the Gospel of John (which also does not name its author) are strong enough to make the authorship conclusive, and early documents (written on parchment rolls) written by disciples (Irenaeus) of the disciples (Polycarp) of John also make the same claim. So, without going into that documentation, we will assume that part is true.
John was probably living in Ephesus in the latter part of the first century when this was written. He was, in all likelihood, in his eighties or nineties at the time, which explains his many references to “little children.”
Also, when speaking of parchment rolls, F.F. Bruce, in his book The Books and the Parchments, says, “When the roll (of parchment) was wound up, a slip containing the title of the work and the name of the author was usually pasted on the outside. This could easily fall off, leaving the work without a name. It may be that something like this happened to the Epistle to the Hebrews. This Epistle bears no writer’s name, although it was not intended to be an anonymous letter; its recipients no doubt knew quite well who had sent it to them. A number of rolls would be kept together in a cylindrical box, which the Romans called a capsa. If an anonymous roll was kept in a box along with a number of other rolls by a known author, the nameless roll was apt to be credited to that author too. Thus, if the Epistle to the Hebrews was kept along with letters of Paul, it was not unnatural that Paul’s name should come to be attached to it.”
The apostle also appears to have mellowed quite a bit from one of the “Sons of Thunder” that Jesus mentioned when referring to John and his brother James who wanted to bring fire from heaven down on a Samaritan village (see Luke 9:54). He is, at the time of this writing, more of an Apostle of Love and his fiery temperament is more under control, which is a testament to the work of the Holy Spirit and his work of sanctification. We can all be grateful for that work which Paul tells us will be brought to “completion at the day of Jesus Christ” (Philippians 1:6).
John is dealing with certain gnostic or “knowledge” heresies in which some claimed to have special knowledge of God that others did not have. Gnostic is from the Greek word gnosis, which means knowledge. They were like those today who claim to have special, mystical insights and revelations (private messages) from God that the rest of the body of Christ did not have—think of the health, wealth, and prosperity preachers of today. (Steve Lawson: Absolute Assurance, Survey of 1 John. Available on YouTube.)
These heresies were promoted by men like Cerinthus, whom John encountered in a Roman bathhouse in the city of Ephesus. According to Polycarp, in Irenaeus, Against Heresies, “John, the disciple of the Lord, going to bathe at Ephesus, and perceiving [the heretic] Cerinthus within, rushed out of the bath-house without bathing, exclaiming, ‘Let us fly, lest even the bath-house fall down, because Cerinthus, the enemy of truth, is within.’”
Clement of Alexandria relates how John fearlessly entered the camp of a band of robbers and led its captain, who had once professed faith in Christ, to true repentance (see Who Is the Rich Man that Shall be Saved?). (From John MacArthur’s commentary on 1st John.)
You see, Cerinthus claimed that God’s spirit descended on Jesus at his baptism but left him at the crucifixion.
Gnostics believed in Dualism, which is a separation of the body and the spirit. The body, which is matter, is evil, and the spirit, which is good. Consequently, they rejected the humanity of Christ, the virgin birth of Christ, they denied that Jesus lived a perfect life in his human body, they denied the validity of Christ’s death on the cross, and they denied the fact that Jesus was resurrected from the dead. They essentially gutted all the core beliefs of Christianity, and so they preyed on Christians to pull them away into their false belief system by claiming that their “knowledge” was superior to the word of God and that whatever the body does is irrelevant to salvation as long as your heart is in the right place. So, Christ’s call to obedience was irrelevant and unimportant.
JMac: John combats the dualism of false teachers who asserted that the “Christ-spirit” departed from the man Jesus just prior to His death on the cross. John writes to show that God has given testimony to the deity of Jesus through both His baptism and death.
