I will be quoting from a book by N.L.Rice :God Sovereign and Man Free, or the Doctrine of Divine Foreordination and Man's Free Agency,Stated,Illustrated and Proved From the Scriptures. But Arminianism rejects the doctrine of "effectual calling." God gave to A. and B.the same call. A.obeyed the call and came to Christ, and B. refused. Now, if Paul should ask A.,as he asked the Corinthian believers, "Who maketh thee to differ from another?and what hast thou that thou didst not receive?" he might answer, 'I make myself to differ from B. He had the same call that I had. He chose to reject it;I chose to accept it. I have,therefore, something which I did not receive.' And indeed upon this thing which he did not receive,his salvation depended. It is impossible that this view of the subject can produce humility so deep,or such a degree of gratitude,as that which ascribes the work to the Holy Spirit.
