Calvin makes a good point about God's general nature being revealed by the Creation, but His specific nature is revealed to us in the Scriptures.
I don't agree with the sentiment above that says the Bible was only given to bring SOME to salvation.
For, seeing how the minds of men were carried to and fro, and found no certain resting-place, he chose the Jews for a peculiar people, and then hedged them in that they might not, like others, go astray.
Hmm, but the Jewish people DID go astray as any cursory reading of the OT will show.
But it is true IF you take the word of God as infallible..
If it was intended to bring all to a saving knowlege then it would do just that
Isa 55:11 So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper [in the thing] whereto I sent it.
Which is true Ksen?
