1-john 5:12

He that hath the Son hath life - As the eternal life is given In the Son of God, it follows that it cannot be enjoyed without him. No man can have it without having Christ; therefore he that hath the Son hath life, and he that hath not the Son hath not life. It is in vain to expect eternal glory, if we have not Christ in our heart. The indwelling Christ gives both a title to it, and a meetness for it. This is God's record. Let no man deceive himself here. An indwelling Christ and Glory; no indwelling Christ, No glory. God's record must stand.

He that hath the Son, hath life - See the notes at John 5:24. John evidently designs to refer to that passage in the verse before us, and to state a principle laid down by the Saviour himself. This is the sense of all the important testimony that had ever been borne by God on the subject of salvation, that he who believes in the Lord Jesus already has the elements of eternal life in his soul, and will certainly obtain salvation. Compare the notes at John 17:3.

And he that hath not the Son of God, hath not life - He that does not believe on him will not attain to eternal life. See the John 3:36 note; Mark 16:16 note.

5:12 It plainly follows, he that hath the Son - Living and reigning in him by faith. Hath this life; he that hath not the Son of God hath not this life - Hath no part or lot therein. In the former clause, the apostle says simply, the Son; because believers know him: in the latter, the Son of God; that unbelievers may know how great a blessing they fall short of.
