People ignorant to the Holy Spirit will not be saved. If you are truly seeking, you shall find. NOBODY can convert anyone.
It is only through the Holy Spirit that you can come to Christ and be saved. Mock the Holy Spirit and there is no hope for you!
That is what FAITH is all about. You have to believe even though it cannot be seen with the physical eye. If you look at Jesus and Scripture and and in the Sacraments (I am Catholic) you will find a God of love and Jesus to be the way the truth and the life.
Supernatural experiences are very very rare so we cant wholly count on them as reason to believe.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
