this has got nothing to do with the fact that Calvin believed that Jesus Christ died for the entire human race, as is very clear from his own words on John 3:16!
All Calvin is saying here, is that God opens the eyes of the elect so that they can believe. This does not mean that Jesus died only for the elect
Calvin on:
John 1:29;
“
Who taketh away the sin of the world. He uses the word sin in the singular number, for any kind of iniquity; as if he had said, that every kind of unrighteousness which alienates men from God is
taken away by Christ. And when he says,
the sin Of The World, he extends this favor
indiscriminately to the whole human race; that the Jews might not think that he had been sent to them alone. But hence we infer that
the whole world is involved in the same condemnation; and that as
all men without exception are guilty of unrighteousness before God, they need to be reconciled to him. John the Baptist, therefore, by speaking generally of
the sin of the world, intended to impress upon us the conviction of our own misery, and to exhort us to seek the remedy. Now our duty is, to embrace the benefit which is
offered to all, that
each of us may be convinced that there is nothing to hinder him from obtaining reconciliation in Christ, provided that he comes to him by the guidance of faith.”
Romans 5:18;
“He makes this favor
common to all, because it is propounded to
all, and not because it is in reality extended to
all; for though Christ
suffered for the sins of the whole world, and is offered through God's benignity
indiscriminately to all, yet all do not receive him”
Mark 14:24;
“
Which is shed for many. By
the word many he means
not a part of the world only, but
the whole human race”
These are plain so that you cannot twist what they say!
