“And this is the record, that God hath giuen to vs eternall life, and this life is in his Sonne.”
1611 King James Version (KJV)
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.
1Jo 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.
