If you had read all of my post, doubtful, you would have seen that I also have proof through the Holy Spirit.
That proof involves faith, and a willingness to to work with God.
When the pot boils down, it's blind faith. There is nothing you can hold in your hand and say, "look Atheists, here it is, the facts you require and must see, here it is.
If you evidence the proper faith in God, and prove that faith by turning at His reproof, that is when God will settle it all in your heart.
The fears, the doubts, the agony of it all is taken away. You're left with peace no matter what's going on with others.
