I have seen several non-Calvinists use this phrase on the boards recently . Over the weekend a number of books arrived . One is called " Sermons That Shaped America . " All of the sermons were delivered by Presbyterians with the exception of Jonathan Edwards , who was a Congregationalist . Afterall ,the book was put out by P&R . James Boice's sermon on the subject heading was the next-to-last entry . Dr.Boice was one of the best American preachers in the last third of the 20th century . He went to glory in June of 2000 . This sermon was delivered in 1999 . I will give some brief quotations . One week , after I had preached a sermon from John touching on some of the main points of the Reformed faith , I found a bulletin from the service upon which someone had scribled his opinion of the message . It said , " I'm sick of Calvinism in every sermon . " The message did not particularly bother me . Notes like that seldom do . But I found it surprising that the person who wrote the note somehow regarded Calvinism as a system of thought that could well be dispensed with while nevertheless , as he assumed , still preserving Christianity . In other words , this person , like many others , somehow regarded the doctrines that go by the name of Calvinism as at best an addition to the pure gospel and at worst a system which is opposed to it . Is this true ? Are the doctrines of grace wrong ? One proof that they are not is seen in the verses to which we come in this chapter . [ John 10:27-29 ] The verses I have in mind are those in which the Lord Jesus Christ spoke plainly to his enemies , saying that those who do not believe on him do not believe because they are not his sheep , that those who are his sheep believe and follow , that this is true because they are given to him by the Father , that these who are given to him by the Father inevitably come to him , and finally , that these who come will never be lost . This is a message of man's complete ruin in sin and God's perfect remedy in Christ , and it can be expressed in the distinctive points of Calvinistic theology . Before we look at these points in detail , however , we should see that far from being an aberration or addition to the gospel , these truths have always belonged to the core of the Christian proclamation and have been characteristic of the church at its greatest periods .
