Whatever ends God has purposed, He has purposed all the means which are necessary for their accomplishment. Why does the farmer till his ground and sow his seed? He knows that HE CANNOT CAUSE SEED TO VEGETATE AND GROW! But he knows that if God gives the increase, it will be through the instrumentality of these means and that IT IS ONLY IN THE USE OF THESE MEANS that he can hope to receive the increase.
Now we know that all the means used to effect the salvation of people are, IN THEMSELVES, utterly powerless unless God makes them effectual to-the salvation of some. What encouragement was there for the prophet Ezekiel to prophesy to the dry bones unless God had determined in connection with his preaching to give them life? What encouragement can there be to preach the gospel of Christ to those who are dead in trespasses and sins unless GOD HAS DETERMINED TO GIVE EFFICACY to the Word of His grace?
The Lord has a chosen people on this earth; and, as the gospel is the appointed means for effecting the salvation of His people, He will send it to those whom He designs to save. God "had much people in Corinth," and for this reason He sent Paul there to preach the gospel.
