It is a false argument posed by the Calvinists that requires the lost sinner to have spiritual understanding before they can be saved. The only thing the Bible requires is recognition of the lost condition which the Holy Spirit provides in conviction (John 16:8).
I grow weary seeing 21 Egyptian Christians lose their heads for Christ, while our “churches” refuse to give up their Wednesday evenings to study the Word of God. If you are too busy to attend church to hear the teaching of the Word, then you are TOO busy. I am at a loss for words as to how to even begin to compare their faith with ours.
Calvinism is a diverse and complex theological system. When one attempts a study of the system, it doesn’t take long to discover that there are many side roads and many twists and turns in the path to understanding. The problem is complicated by those who hold to the system because there is no single view that all Calvinists accept.
The Calvinists will tend to emphasize the role of “God” in loving the world and giving the Son. The Arminians will tend to stress the word “whosoever” as indicating human freedom and the human decision-making process in salvation.
If I shoot a man without cause, that action would be wrong. But if a police officer shoots a man with cause, then the action would be regarded as justified. The same action is judged differently when it is carried out by different actors in different circumstances.
