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.
10. hath the witness—of God, by His Spirit (1Jo 5:8).
in himself—God's Spirit dwelling in him and witnessing that "Jesus is the Lord," "the Christ," and "the Son of God" (1Jo 5:1, 5). The witness of the Spirit in the believer himself to his own sonship is not here expressed, but follows as a consequence of believing the witness of God to Jesus' divine Sonship.
believeth not God—credits not His witness.
made him a liar—a consequence which many who virtually, or even avowedly, do not believe, may well startle back from as fearful blasphemy and presumption (1Jo 1:10).
believeth not the record—Greek, "believeth not IN the record, or witness." Refusal to credit God's testimony ("believeth not God") is involved in refusal to believe IN (to rest one's trust in) Jesus Christ, the object of God's record or testimony. "Divine "faith" is an assent unto something as credible upon the testimony of God. This is the highest kind of faith; because the object hath the highest credibility, because grounded upon the testimony of God, which is infallible" [Pearson, Exposition of the Creed]. "The authority on which we believe is divine; the doctrine which we follow is divine" [Leo].
gave—Greek, "hath testified, and now testifies."
of—concerning.
