That Non Imputation of sin to God's Elect World is an Gospel Doctrine is seen in Paul's Preaching here 2 Cor 5:19 19 To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation. We know the World here does not mean everyone without exception, simply because many have their sin imputed to them, like those here Jn 8:24 24 I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins. So how is it possible for these to die in their sins if they had not been imputed to their charge ? So it is quite reasonable to conclude that they belonged not to the World of 2 Cor 5:19 ! But that there is a World that sin, trespasses were not charged to, and Paul preached of, is clearly seen here in 2 Cor 5:19 and there is no Gospel message without this Truth and the explaining of it !
