Charles Spurgeon Commentary 1 John 5:12

"He that hath the Son hath the life; he that hath not the Son of God hath not the life." — 1 John 5:12 (ASV)

He that hath the Son hath life; and he that hath not the Son of God hath not life.

You exist, and you always will exist, but true life is not yours if you have not Christ as your Saviour. Life is something infinitely superior to mere existence: He that hath the Son hath life; and he that hath not the Son of God hath not life.
