John 1:16

The testimony of the Baptist to the incarnate Word is confirmed by the experience of all believers. The Evangelist is the speaker.

And The true reading gives Because.

fullness The Greek word, pleroma, is -a recognised technical term in theology, denoting the totality of the Divine powers and attributes." This fulness of the Divine attributes belonged to Christ (John 1:14), and by Him was imparted to the Church, which is His Body (Ephesians 1:23); and through the Church each individual believer in his degree receives a portion of it. See Lightfoot on Colossians 1:19; Colossians 2:9. -Of His fulness" means literally - out of His fulness," as from an inexhaustible store.

all we shews that the Evangelist and not the Baptist is speaking.

grace for grace Literally, grace in the place of grace, one grace succeeding another, and as it were taking its place. There is no reference to the Christian dispensation displacing the Jewish. The Jewish dispensation would have been called -the Law," not -grace;" see next verse, and comp. John 17:22.
