Commentators like Albert Barnes and John Calvin highlight that this verse balances God's sovereign will (v. 39) with human responsibility. While God gives people to the Son, the clear, revealed will of the Father is that salvation comes to the one who actively "sees" and "believes" in the Son. Faith is presented not as a work that earns salvation, but as the necessary response and evidence that one belongs to God, preventing any misuse of the doctrine of election for passivity or presumption.
