Commentaries:
Robertson's Word Pictures (NT)
Except it be given him of the Father (ean mh h dedomenon autw ek tou patrov). Condition of third class with ean mh and periphrastic perfect passive subjunctive of didwmi. Precisely the same point as in verse John 6:44 where we have elkush instead of h dedomenon. The impulse to faith comes from God. Jesus does not expect all to believe and seems to imply that Judas did not truly believe.
