The Great Commentary of Cornelius à Lapide
1 John 1:12
He that hath the Son, i.e., by faith, love, and obedience, hath life, of grace in fact, of glory in hope. He alludes to the words in his own Gospel, "He that believeth in the Son hath everlasting life, but he that believeth not the Son shall not see life, but the wrath of God abideth on him." (John 3:35.)
