SEV Biblia, Chapter 4:15
Cualquiera que confesare que Jesús es el Hijo de Dios, Dios permanece en él, y él en Dios.
Clarke's Bible Commentary - 1 John 4:15
Verse 15. Whosoever shall confess] Much stress is laid on this confession, because the false teachers denied the reality of the incarnation; but this confession implied also such a belief in Christ as put them in possession of his pardoning mercy and indwelling Spirit.
Matthew Henry Commentary
Verses 14-21 - The Father sent the Son, he willed his coming into this world. The apostle attests this. And whosoever shall confess that Jesus is the So of God, God dwelleth in him, and he in God. This confession include faith in the heart as the foundation; makes acknowledgment with the mouth to the glory of God and Christ, and profession in the life an conduct, against the flatteries and frowns of the world. There must be a day of universal judgment. Happy those who shall have holy boldnes before the Judge at that day; knowing he is their Friend and Advocate Happy those who have holy boldness in the prospect of that day, wh look and wait for it, and for the Judge's appearance! True love to God assures believers of God's love to them. Love teaches us to suffer for him and with him; therefore we may trust that we shall also be glorified with him, 2Ti 2:12. We must distinguish between the fear of God and being afraid of him; the fear of God imports high regard an veneration for God. Obedience and good works, done from the principl of love, are not like the servile toil of one who unwillingly labour from dread of a master's anger. They are like that of a dutiful child who does services to a beloved father, which benefit his brethren, an are done willingly. It is a sign that our love is far from perfect when our doubts, fears, and apprehensions of God, are many. Let heave and earth stand amazed at his love. He sent his word to invite sinner to partake of this great salvation. Let them take the comfort of the happy change wrought in them, while they give him the glory. The love of God in Christ, in the hearts of Christians from the Spirit of adoption, is the great proof of conversion. This must be tried by it effects on their temper, and their conduct to their brethren. If a ma professes to love God, and yet indulges anger or revenge, or shows selfish disposition, he gives his profession the lie. But if it is plain that our natural enmity is changed into affection and gratitude let us bless the name of our God for this seal and earnest of eterna happiness. Then we differ from the false professors, who pretend to love God, whom they have not seen, yet hate their brethren, whom the have seen __________________________________________________________________
