William Burkitt on John 17:8

As if Christ had said, "The message by thee my Father committed to me, I have communicated to them my disciples, and they have received it, and will communicate it from thee to the world; being sufficiently assured that my coming and preaching was all by commission from thee."

Hence learn, 1. That the doctrine of the gospel, which was revealed by Christ, was received from the Father.

2. That faith is a receiving of the word of Christ, and of Christ in and by the word. Receiving is a relative term, and presupposes an offer. God offers on his part, and we receive on our part, the whole word with the whole heart. That the ministers of the gospel are to preach that, and only that, which they have out of the word of God: I have given them the word which thou gavest me.
