If God was a Calvinist He would be spreading a lie. The scripture says Num 23:19 God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good? If God was to declare that He was not willing that any should perish, and a doctrine said that He was willing that many perish, that doctrine would accuse God of telling a lie. Thank God the truth is that whoever will, may come and be saved and not a distinct chosen few.
