In context..scripture not Calvin.
But people who aren’t spiritual can’t receive these truths from God’s.
It all sounds foolish to them and they can’t understand it,for only those who are spiritual can understand what the Spirit means...1 Corinthians 2:14..
The natural man does not accept the things of the Spirit of God,for they are folly to him,and he is not able to understand them because they are spiritually discerned.
So,through faith,is a natural man a born again? ..from reading your posts you seem to think they are.
Surely I’m mistaken?
