There is no need, because you are evading my points. A person cannot hear or believe God's Words in a Lost state 2 Cor 4:3-4 ; Jn 8:47 ; Rom 8:8
Ripping scripture out of context is not the way to prove your point.
What was Jesus demonstrating in John 8?
John 8:47 He that is of God heareth God's words: ye therefore hear them not, because ye are not of God.
--They were not of God, IOW, not true believers, or not true Jews. They called themselves Pharisees but unlike the Apostles they did not believe. Now look at the contrast Jesus makes.
John 8:56 Your father Abraham rejoiced to see my day: and he saw it, and was glad.
--In contrast to the Jews, the father of their nation (whom they said they were the children of) was a believing "Jew". He put his faith in Jehovah, whereas they didn't. This is the comparison he was making.
--
In no way does this teach that the gospel is to believers only.
CONTEXT!!
Again look at the context:
Romans 8:7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
8 So then they that are in the flesh cannot please God.
Paul is writing to believers, not the lost.
The teaching here is that
Carnal Christians cannot please God.
What you do in the flesh cannot please God. When you pray, and your mind is elsewhere, or if it just for show, it does not please God. This is directed to believers.
James 4:4 teaches the same thing and is worded even with stronger language than this:
James 4:4 Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God?
whosoever therefore will be a friend of the world is the enemy of God.
--Doing things of the flesh, living like the world; James says you are the enemy of God even though you are a Christian. How is that for an indictment. Go ahead: smoke your cigarette; drink your alcoholic beverage; go to the bar; live it up. God says you are the enemy of God. That is the Christian "who is in the flesh and cannot please God." He is writing to believers.
CONTEXT!!
You made mention that Paul was ready to preach to all in Rome Rom 1:15
15 So, as much as in me is, I am ready to preach the gospel to you that are at Rome also.
Yes, the Gospel can be preached to everyone in sight, however its only designed in the purpose of God to be a word of Salvation to the saved !
Can be??
It is commanded to be!
"Go ye into all the world and preach the gospel to every creature."
The Great Commission commands us to go and preach the gospel to ALL that are in the world, not just the elect. Certainly it is efficacious only to those believe. Both Cals and non-Cals alike believe that.
When a sower goes out to sow the word of God, the word lands upon different types of soils, but only one soil does it bear fruit upon, the good soil Matt 13:23
No argument, but it has to be sown on all types of soil, doesn't it?
23 But he that received seed into the good ground is he that heareth the word, and understandeth it; which also beareth fruit, and bringeth forth, some an hundredfold, some sixty, some thirty.
You are making my point. It is sown to all soils. We are witnesses. It is God that gives the increase.
Now many hear it but dont understand it, because its not received into good ground, which I believe stands for a new heart !
So you can get all the scripture you want, not one of them will affirm that a Lost person can hear, understand and believe the Gospel !
It is our duty to preach the gospel. It is our duty to witness to the lost (Acts 1:8). We must plant, water, but it is God that gives the increase.
