I know plenty of once lost hardened sinful people who were saved and changed their lives after being confronted with their lost sinful condition and the gospel. So chose it and some rejected it.
Either way; however, the bible is full of real life examples in which Jesus and His apostles confront people and win some of them over because they loved God, loved the truth, and loved the people around them enough to boldly tell them the truth so they could have an opportunity to be saved and changed into "new creatures."
Your assertion that confronting people is never the right way to win them over is unbiblical and false.
Study Paul's homiletics. He is directly confrontational engaging pagans with their deceived lost immoral condition and God's prescription for it in the gospel of Jesus Christ. Paul repeatedly states that there is a living loving holy creator God as opposed to the worthless idols that never show their power as he confronts pagans in his missionary journeys right where they are in their deception and sin.
For example,
in Lystra, Paul attacks their false pagan gods as worthless things. This is even more powerful when you realize that the priests of Zeus have brought out bulls to sacrifice to Paul and Barnabas because they had mistaken him for one of their fabricated pagan gods due to the healing miracles he worked through the power of God in that city. Paul points at these prepared sacrifices when he says, “worthless idols.” The noun used here (μάταιος) means that these idols and their sacrifices “lack truth” and it is pointless to worship them because they are not true at all.
The citizens of Lystra's reaction to this was to stone him and leave him for dead. On recovering, Paul left for Derbe; but soon returned again, through Lystra, encouraging the disciples there to steadfastness. Timothy, who was probably born in Lystra, witnessed Paul's confrontation and persecution in Lystra and was converted.
You are myopically projecting your own recalciatrance at having someone boldly confront you with the truth publicly as a false teaching that Christians are never supposed to preach the word boldly and that is NOT true. Biblical examples themselves, in both the old and new testament, completely refute your false assertion.
The mission of the prophet and the preacher is all about confronting people with their actual condition, God's prescription for it, and His judgment of it if they reject His provision runs right through both the old and new testament.
Read Stephen's final
speech to the Sanhedrin. Pay attention to verses 51-57:
“'You stiff-necked people! Your hearts and ears are still uncircumcised. You are just like your ancestors: You always resist the Holy Spirit! Was there ever a prophet your ancestors did not persecute? They even killed those who predicted the coming of the Righteous One. And now you have betrayed and murdered him— you who have received the law that was given through angels but have not obeyed it.'
When the members of the Sanhedrin heard this, they were furious and gnashed their teeth at him. But Stephen, full of the Holy Spirit, looked up to heaven and saw the glory of God, and Jesus standing at the right hand of God. 'Look,' he said, 'I see heaven open and the Son of Man standing at the right hand of God.' At this they covered their ears and, yelling at the top of their voices, they all rushed at him, dragged him out of the city and began to stone him."
Perhaps you would have stoned Stephen or Paul or walked off because you were offended at what they boldly and publicly proclaimed and in the manner they proclaimed it but there it is right at the heart of the bible's homiletic.
Instead of falling into the error of misrepresenting what actually happens in the bible so it can comport with your own egoist feelings, you need to read it and see what's actually happening as God's ministers move in the world moved by God and adjust to that.
Being confrontational with people is never the right way to win them over. If someone is confrontational with me that I'm either going to react aggressively or I'm going to walk away and ignore them.
