5:11 {12} And this is the record, that God hath given to us eternal life, and this life is in his Son.
(12) Now at length he shows what this testimony is that is confirmed with so many witnesses: that is, that life or everlasting happiness is the gift of God, which is the Son, and proceeds from him to us, who by faith are joined with him, so that without him, life is nowhere to be found.
5:11 This is the record. God gives us eternal life through this Son. We know that we have it because we know that we have a new life.
5:11 And this is the sum of that testimony, that God hath given us a title to, and the real beginning of, eternal life; and that this is purchased by, and treasured up in, his Son, who has all the springs and the fulness of it in himself, to communicate to his body, the church, first in grace and then in glory.
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.
