John 20:31

Verse 31. These are written. Those recorded in this gospel.

That ye might believe, &c. This is a clue to the design which John had in view in writing this gospel. The whole scope or end of the book is to accomplish two objects:

1st. To prove that Jesus was the Messiah; and,

2nd. That they who looked at the proof might be convinced and have eternal life. This design is kept in view throughout the book. The miracles, facts, arguments, instructions, and conversations of our Lord all tend to this. This point had not been kept in view so directly by either of the other evangelists, and it was reserved for the last of the apostles to collect those arguments, and make out a connected demonstration that Jesus was the Messiah. If this design of John is kept steadily in view, it will throw much light on the book, and the argument is unanswerable, framed after the strictest rules of reasoning, infinitely beyond the skill of man, and having throughout the clearest evidence of demonstration.

(i) "But these are written" Lk 1:4

Romans 3:3

Verse 3. For what if some did not believe? This is to be regarded as another objection of a Jew. "What then? or what follows? if it be admitted that some of the nation did not believe, does it not fallow that the faithfulness of God in his promises will fail?" The points of the objection are these:

(1.) The apostle had maintained that the nation was sinful, (chapter 2;) that is, that they had not obeyed or believed God.

(2.) This the objector for the time admits, or supposes, in relation to some of them. But

(3) he asks whether this does not involve a consequence which is not admissible, that God is unfaithful. Did not the fact that God chose them as his people, and entered into covenant with them, imply that the Jews should be kept from perdition? It was evidently their belief that all Jews would be saved--and this belief they grounded on his covenant with their fathers. The doctrine of the apostle (chapter 2) would seem to imply that, in certain respects, they were on a level with the Gentile nations; that ff they sinned, they would be treated just like the heathen; and hence they asked of what value was the promise of God ? Had it not become vain and nugatory?

Make the faith. The word faith here evidently means the faithfulness or fidelity of God to his promises. Comp. Mt 23:23, 2Ti 3:10, Hos 2:20.

Without effect. Destroy it; or prevent him from fulfilling his promises. The meaning of the objection is, that the fact supposed, that the Jews would become unfaithful and be lost, would imply that God had failed to keep his promises to the nation; or that he had made promises which the result showed he was not able to perform.

(n) "some did not believe" Rom 10:16, Heb 4:2
