1 John 5:6-8 - water and blood

5:6-8

“Who came by water and blood”, water possibly refers to baptism, or possibly it refers to natural birth, blood refers to the cross. Taking the baptism and cross it refers to the beginning of His ministry, and the cross to the end, taking the birth and cross combination, it refers to his humanity and death. I personally think the latter fits the context better. John then says that there are three that testify, the Spirit, the water and the blood, and they are in agreement. All three are vital, and to deny any one of them is to deny everything. The Holy Spirit testifies about Jesus, he is fully human (the incarnation), and He shed His  blood on the cross for our sakes. 

1 John 5:1-5 - Loving the Father and the Son

5:1-3

Loving the Father and loving the Son are one and the same thing, they are inseparable, you cannot claim to love one and not the other. Some who do not love God claim to love Him and His children, but the only way to truly love people is to love God and carry out His commands. Loving God and obeying His commands go together and are inseparable. Jesus spoke about loving Him and obeying His teaching (John 14:23).

5:4,5

“Everyone born of God overcomes the world”. The world is opposed to God, so we face opposition, but if we are born of God we overcome the world. We overcome the world by believing that Jesus is the Son of God, not by going along with the world. Believing that Jesus is the Son of God is crucial.

1 John 4:13-21 - Love

4:13-16

The Holy Spirit is absolutely essential. He assures us that we live in Him. Acknowledging that Jesus is the Son of God is a crucial sign too. Jesus is the focus of all the Father’s plans, so we testify that the Father sent His Son to be the saviour of the world. “So we know and rely on the love God has for us”. What we believe matters, but it is also a relationship, a love relationship with God.

4:17,18

We will have confidence on the day of judgement because of God’s love for us. False teachers often rely on fear, but perfect love drives out fear. “Fear has to do with punishment”. The cross has paid the price for us, Jesus took on Himself the punishment that should have been ours, so we have no fear. God’s love drives out fear.

4:19-21

God’s love for us is the starting point, we love in response to His love for us. Again John points out that hating a brother or sister is incompatible with loving God. How can we say we love God who is unseen if we do not love a brother or sister who we can see?

1 John 4:7-12 - This is love

4:7-12

Love comes from God. This is one of the arguments for the Trinity, for it is because God exists as three persons that love could exist between these persons. So love if we are born of God. Conversely if we do not love then any claim to know God is spurious. The supreme demonstration of His love for us was His sending of His son, so that we “might live through Him”. The Son was sent as an atoning sacrifice. There are some ignorant people who refer to this as “cosmic child abuse”, but such people only demonstrate their own stupidity and ignorance. The Father and Son were in complete agreement. God’s love for us is the starting point, any love we have for Him followed on from that. We also ought to love one another. Love is the essential proof that God lives in us.

1 John 4:1-6 - The Test

4:1-3

We now come to what is probably the most theological part of the letter, focusing on the incarnation. It is interesting that John is clearly concerned with lifestyle and behaviour, “Loving one another”, but this does not diminish his concern with right theology. Indeed most false teachings fail to get the person of Jesus Christ right, denying either His humanity or His divinity. It is worth noting that most early heresies tended to deny His humanity. John begins this section with a test to see whether or not a spirit is from God. He also recognises that many false prophets have gone into the world. The key test here is whether a spirit “acknowledges that Jesus Christ has come in the flesh”, i.e. the humanity of Jesus. Any spirit that does not acknowledge this is not from God, indeed it is the spirit of the antichrist, and the spirit of antichrist is already in the world.

4:4-6

The Holy Spirit bears witness to the humanity of Christ, and He is in us. If we believe the gospel then we have overcome the spirit of anti-Christ, for the Holy Spirit is greater than the spirit who is in the world. We should not be surprised if the world listens to the anti-Christ, for the anti-Christ is the spirit of the world, and speaks from the viewpoint of the world. If we believe the gospel we are from God, for we are born again of God.

1 John 3:19-24 - Believing in the Son, and loving one another

3:19-24

The change in our lives shows that we belong to the truth, despite what  anyone else may try to tell us. Note that our experience is seen as important. Even so, it may be that we still feel condemned. In that case “we know that God is greater than our hearts. He knows everything, and He sent Jesus to die on the cross for us knowing just what we were like. Note that there is an interplay between theological truth and our experience. It is better when we do not feel condemned, and this gives us greater confidence in prayer. Our actions and obedience do matter. The primary command of God the Father is to “believe in His Son, Jesus Christ, and to love one another”.and the Holy Spirit attests to the truth of this.

1 John 3:11-18 - Love one another

3:11-15

John places a great deal of emphasis on loving one another. He goes right back to Cain as to why this matters so much. Cain “belonged to the evil one”, he murdered his brother because Abel’s action showed up his own failures. Likewise the world hates us, and this should come as no surprise.In repenting and believing in Christ we have done “the right thing”, so the world that is in rebellion does not take kindly to us. 

Loving each other (or not) is a key indicator of whether or not we have passed from death to life.

3:16-18

Jesus laying down his life for us is the prime example of love, we should act towards our brothers and sisters in Christ in the same way. This includes sharing our material possessions, it will not always be as grand a matter as actually dying for someone. Love is not just a matter of words and feelings, but of deeds and action.
