51 Whoever believes that Jesus is the Christ is born of God, and everyone who loves Him who begot also loves him who is begotten of Him. 2 By this we know that we love the children of God, when we love God and keep His commandments. 3 For this is the love of God, that we keep His commandments. And His commandments are not burdensome. 4 For whatever is born of God overcomes the world. And this is the victory that has overcome the world--our faith. 5 Who is he who overcomes the world, but he who believes that Jesus is the Son of God?
6 This is He who came by water and blood--Jesus Christ; not only by water, but by water and blood. And it is the Spirit who bears witness, because the Spirit is truth. 7 For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one. 8 And there are three that bear witness on earth: the Spirit, the water, and the blood; and these three agree as one. 9 If we receive the witness of men, the witness of God is greater; for this is the witness of God which He has testified of His Son.
10 He who believes in the Son of God has the witness in himself; he who does not believe God has made Him a liar, because he has not believed the testimony that God has given of His Son. 11 And this is the testimony: that God has given us eternal life, and this life is in His Son. 12 He who has the Son has life; he who does not have the Son of God does not have life.

(Read 1 John 5:1-5)
True love for the people of God, may be distinguished from natural kindness or party attachments, by its being united with the love of God, and obedience to his commands. The same Holy Spirit that taught the love, will have taught obedience also; and that man cannot truly love the children of God, who, by habit, commits sin or neglects known duty. As God's commands are holy, just, and good rules of liberty and happiness, so those who are born of God and love him, do not count them grievous, but lament that they cannot serve him more perfectly. Self-denial is required, but true Christians have a principle which carries them above all hinderances. Though the conflict often is sharp, and the regenerate may be cast down, yet he will rise up and renew his combat with resolution. But all, except believers in Christ, are enslaved in some respect or other, to the customs, opinions, or interests of the world. Faith is the cause of victory, the means, the instrument, the spiritual armour by which we overcome. In and by faith we cleave to Christ, in contempt of, and in opposition to the world. Faith sanctifies the heart, and purifies it from those sensual lusts by which the world obtains sway and dominion over souls. It has the indwelling Spirit of grace, which is greater than he who dwells in the world. The real Christian overcomes the world by faith; he sees, in and by the life and conduct of the Lord Jesus on earth, that this world is to be renounced and overcome. He cannot be satisfied with this world, but looks beyond it, and is still tending, striving, and pressing toward heaven. We must all, after Christ's example, overcome the world, or it will overcome us to our ruin.
Commentary on 1 John 5:6-8
(Read 1 John 5:6-8)
We are inwardly and outwardly defiled; inwardly, by the power and pollution of sin in our nature. For our cleansing there is in and by Christ Jesus, the washing of regeneration and the renewing of the Holy Ghost. Some think that the two sacraments are here meant: baptism with water, as the outward sign of regeneration, and purifying from the pollution of sin by the Holy Spirit; and the Lord's supper, as the outward sign of the shedding Christ's blood, and the receiving him by faith for pardon and justification. Both these ways of cleansing were represented in the old ceremonial sacrifices and cleansings. This water and blood include all that is necessary to our salvation. By the water, our souls are washed and purified for heaven and the habitation of saints in light. By the blood, we are justified, reconciled, and presented righteous to God. By the blood, the curse of the law being satisfied, the purifying Spirit is obtained for the internal cleansing of our natures. The water, as well as the blood, came out of the side of the sacrificed Redeemer. He loved the church, and gave himself for it, that he might sanctify and cleanse it with the washing of water by the word; that he might present it to himself a glorious church, Ephesians 5:25-27. This was done in and by the Spirit of God, according to the Saviour's declaration. He is the Spirit of God, and cannot lie. Three had borne witness to these doctrines concerning the person and the salvation of Christ. The Father, repeatedly, by a voice from heaven declared that Jesus was his beloved Son. The Word declared that He and the Father were One, and that whoever had seen him had seen the Father. And the Holy Ghost, who descended from heaven and rested on Christ at his baptism; who had borne witness to Him by all the prophets; and gave testimony to his resurrection and mediatorial office, by the gift of miraculous powers to the apostles. But whether this passage be cited or not, the doctrine of the Trinity in Unity stands equally firm and certain. To the doctrine taught by the apostles, respecting the person and salvation of Christ, there were three testimonies. 1. The Holy Spirit. We come into the world with a corrupt, carnal disposition, which is enmity to God. This being done away by the regeneration and new-creating of souls by the Holy Spirit, is a testimony to the Saviour. 2. The water: this sets forth the Saviour's purity and purifying power. The actual and active purity and holiness of his disciples are represented by baptism. 3. The blood which he shed: and this was our ransom, this testifies for Jesus Christ; it sealed up and finished the sacrifices of the Old Testament. The benefits procured by his blood, prove that he is the Saviour of the world. No wonder if he that rejects this evidence is judged a blasphemer of the Spirit of God. These three witnesses are for one and the same purpose; they agree in one and the same thing.
Commentary on 1 John 5:9-12
(Read 1 John 5:9-12)
Nothing can be more absurd than the conduct of those who doubt as to the truth of Christianity, while in the common affairs of life they do not hesitate to proceed on human testimony, and would deem any one out of his senses who declined to do so. The real Christian has seen his guilt and misery, and his need of such a Saviour. He has seen the suitableness of such a Saviour to all his spiritual wants and circumstances. He has found and felt the power of the word and doctrine of Christ, humbling, healing, quickening, and comforting his soul. He has a new disposition, and new delights, and is not the man that he formerly was. Yet he finds still a conflict with himself, with sin, with the flesh, the world, and wicked powers. But he finds such strength from faith in Christ, that he can overcome the world, and travel on towards a better. Such assurance has the gospel believer: he has a witness in himself, which puts the matter out of doubt with him, except in hours of darkness or conflict; but he cannot be argued out of his belief in the leading truths of the gospel. Here is what makes the unbeliever's sin so awful; the sin of unbelief. He gives God the lie; because he believes not the record that God gave of his Son. It is in vain for a man to plead that he believes the testimony of God in other things, while he rejects it in this. He that refuses to trust and honour Christ as the Son of God, who disdains to submit to his teaching as Prophet, to rely on his atonement and intercession as High Priest, or to obey him as King, is dead in sin, under condemnation; nor will any outward morality, learning, forms, notions, or confidences avail him.
