4 For all that has been begotten of God gets the victory over the world; and this is the victory which has gotten the victory over the world, our faith. v.4 Overcoming the World. Every child of God, everyone with eternal life, overcomes the world-system. How? By faith which has an object higher than this world: the Son of God (Gal. 2:20). Some in practice do not overcome, but the victory is theirs for the taking.

5 Who is he that gets the victory over the world, but he that believes that Jesus is the Son of God? v.5 A New Object for Faith The world is really the great obstacle in the Christian’s path which prevents him from obeying the commandments of God (1 John 2:16). But faith, like a grain of mustard seed, can remove such a great mountain and cast it into the sea. How does this work? Our faith has an object which has overcome the world. The Christian believes that Jesus – whom the world has crucified – is the Son of God. In this way our faith has a practical victory over this world.

6 This is he that came by water and blood, Jesus the Christ; not by water only, but by water and blood. And it is the Spirit that bears witness, for the Spirit is the truth. v.6 Blood, Water & the Spirit’s Witness. We had the new object for faith in v.5 (Jesus, the Son of God), and now we have the work that our object accomplished. When it speaks of Christ “coming” it doesn’t refer to the incarnation (the water and blood of childbirth), but to the great purpose for which Jesus came; to deal with the issue of sin.

When the spear pierced the side of a dead Christ, both blood and water flowed out. Blood speaks of the judicial cleansing from the guilt of sin. Water speaks of the moral cleansing from the defilement of sin. Not only has the work of Christ justified us (blood) but it has also cleansed us (water) in God’s sight, in the sight of others, and in my own sight. e.g. this is how Peter could say in his Pentecostal sermon, "whom ye (Israel) have denied". Peter was clean in his own sight as well as others. It says that Christ came "by water and by blood", that is for the purpose of effecting moral and judicial cleansing (sanctification and justification).¹ The Spirit of God bears witness to that. John emphasizes "not by water only". It was not the Lord's purpose in coming only to cleanse His people from moral defilement, but also to give God a righteous basis to declare us judicially "just" in His sight (Rom. 3:26). One who is only morally cleansed is not a finished product. There are many religions in the world that profess to be able to wash with water; that is, to produce a holy life. These religions are unable to wash with water, but one thing they cannot even attempt to do is wash with blood. They cannot even grasp how the guilt of sin can be put away, and how a sinner can be justified in God’s sight. Christ came, not by water only, but by water and blood. It is a distinctive characteristic of Christianity. In 1 John 5 the water is mentioned before the blood because that is the order in which they are applied to a believer. We must be born again first, then we believe on the only-begotten Son for eternal life. Even in Old Testament typology, the sons of Aaron were washed with water first, then sprinkled with blood (Lev. 8). But in John 19:34 the blood is mentioned before water because that was the order they came out in historically, and the order which has God's interests first, before man's need. The Spirit bears witness (1 John 5:6) and makes both things good to the believing soul, so that all three agree in one!

 

7 For they that bear witness are three: 8 the Spirit, and the water, and the blood; and the three agree in one. vv.7-8 Three in One. There are three witnesses that God has give us eternal life. The water and blood from the pierced side of Christ, and the Spirit sent down after He was glorified. The order of the three witnesses is changed because this is the order in which we apprehend it. God’s three witnesses to His gift of eternal life: (1) the Spirit – enables us to appreciate both, (2) water – moral purification and new birth, and (3) blood – expiation for sin. John takes up these three great witnesses in his ministry.

 

9 If we receive the witness of men, the witness of God is greater. For this is the witness of God which he has witnessed concerning his Son. 10 He that believes on the Son of God has the witness in himself; he that does not believe God has made him a liar, because he has not believed in the witness which God has witnessed concerning his Son. 11 And this is the witness, that God has given to us eternal life; and this life is in his Son. 12 He that has the Son has life: he that has not the Son of God has not life. vv.9-12 The Unified Witness of God. the witness of men, like apostles in ch1? Inner witness of gbd Spirit. Witness of the word (v.13). We have life in association with the son. He that hath the son hath life.

13 These things have I written to you that ye may know that ye have eternal life who believe on the name of the Son of God. v.13 Consciousness of the Possession of Eternal Life. This is the end of the doctrinal part of the epistle. John now begins to use a different word for “know”. Before this it was the work ‘ginosko’ or objective knowledge. Now he begins to use the word ‘oida’, which is the inward personal knowledge of conviction. He used this word through v.21 for a total of five times. The first thing he mentions that the believer knows is that he has eternal life. John tells us that this was one of the great reasons why he wrote the first epistle; that the believer might have the conscious inward knowledge that he presently possesses eternal life.

In scripture there is a difference between "believing", "believing in", and "believing on". If you "believe" someone, you accept what they say as truth. If you "believe in" someone, you have confidence in their character; i.e. it has to do with who they are, although it also includes that they are honest. If you "believe on" someone, they become an object for your faith, and this also includes both confidence in their character and in their words, but goes far higher.

The believer has believed “on the name of the Son of God”, and on that basis they are saved and possess eternal life. 

 

14 And this is the boldness which we have towards him, that if we ask him anything according to his will he hears us. 15 And if we know that he hears us, whatsoever we ask, we know that we have the petitions which we have asked of him. vv.14-15 Knowledge of Access in Prayer. The second thing the believer knows is that he has the “boldness” to petition the Lord and the confidence that those prayers are heard and answered, according to His will. This is a privilege of the whole family of God. This doesn’t mean we will get whatever we pray for. We do not always pray according to the Lord’s will. You might ask, what is the point of praying if the Lord only gives what is according to His will? Prayer is less about changing God and more about changing us to align our thoughts with His! Nevertheless, it is the Lord’s gracious manner to link His own actions with the prayers of His people.

 

16 If any one see his brother sinning a sin not unto death, he shall ask, and he shall give him life, for those that do not sin unto death. There is a sin to death: I do not say of that that he should make a request. 17 Every unrighteousness is sin; and there is a sin not to death. vv.16-17 Intercession for A Sinning Brother. The believer has discernment to know when to intercede and when not to. This is a knowledge that the believer has by communion. If we see our brother sin, we should pray for him. Sometimes, in the government of God, sickness or injury is a result of sin in the lives of believers. This is not always the case. For example, Lazarus was sick and died “for the glory of God, that the Son of God might be glorified thereby” (John 11:4). The blind man in John 9 was born blind, not because he or his parents had sinned, “but that the works of God should be made manifest in him” (John 9:3). It is our privilege to pray for our brethren when they are sick, regardless of why they are sick. But when we see them sin, and then get sick, we are called upon to consider the case. God can give us discernment to know if this is a “sin not unto death”. In that case, we should pray for the brother, and the Lord will “give him life” – i.e. an extension of his natural life, not divine life. But, this is not always the case. “There is a sin to death”. An example would be Ananias and Sapphira. There it was not only a lie, but it was a very serious and brazen lie. In the case where the person has sinned to a point where God has determined to take them home through death, John says “I do not say of that that he should make a request”. He doesn’t prohibit praying in this case, but cannot encourage us to pray against the will of God, when we are clear in our minds as to what it is. When a believer sins a sin unto death, they can still be restored to communion if repentance comes in. There have been cases where a believer has acknowledged that they did sin a sin unto death, and the Lord was honored in the brother or sister’s submission to the Lord’s will. But we are reminded that “every unrighteousness is sin”; and not every sin is a sin to death. See James 5:13-20.

 

18 We know that every one begotten of God does not sin, but he that has been begotten of God keeps himself, and the wicked one does not touch him. v.18 Knowledge of Family Character. The third thing the believer is said to know is what characterized the children in God’s family; “every one begotten of God does not sin”. Clearly, from v.16 it is possible for a child of God to sin, and sin grievously. But that is not what is characteristic of a child of God. Instead, what marks a true believer is moral preservation; “he that has been begotten of God keeps himself”. We do not have the power to keep ourselves. Deliverance from sin is not through human effort. But the believer can keep himself in communion, in the enjoyment of the love of God (Jude 21), and God can use this in our preservation. We do not need to be afraid of the Wicked One. If we remain in communion with the Lord, the Devil has nothing with which to lure us into his snares.

kept by the power of god, through faith

19 We know that we are of God, and the whole world lies in the wicked one. v.19 Knowledge of What We Are and What the World Is. 

20 And we know that the Son of God has come, and has given us an understanding that we should know him that is true; and we are in him that is true, in his Son Jesus Christ. He is the true God and eternal life. v.20 Things we know. Sum of Johns ministry. An understanding… the father revealed. We can know thee, the only true god, and Jesus Christ. The son is the true god, and eternal life. In him… in his son… the life we possess is not independent of him. Kernaks have life in the stalk. Nothing beyond that. You have it all.
