John 17:19-20

John 17:19-20. And for their sakes I sanctify myself, that they also might be sanctified through the truth. Neither pray I for these alone, but for them also which shall believe on me through their word;

That shows that Christ’s prayer embraces us also who have been brought to believe on him through the word which the apostles declared. Christ, with prescient eye, looked on every one of us who believe on him, and prayed for each one of us as much as he did for John, and Peter, and James.
