remove all my doubt about His existence
I read a lot of atheist posts on reddit, and I think where a lot people get diverted is the argument of a loving God allowing evil. This is such a paradox that to an atheist, it's an impossible idea. And in Isaiah it says "I make peace and create evil, I the Lord do all of these things".
This is a telling passage IMHO. Combine this with the idea that Adam and Eve were only kicked out of Eden (a place of perfection) when they learned of "good and evil" and became
like God. This knowledge is what causes us to pass judgments (recall Jesus admonished us not to judge)
From this we know that God knows of good and evil, in Isaiah it goes so far as to say that God actually creates both and it is the knowledge of these opposites that got us kicked out of Eden and causes us continuing suffering. What's interesting to me is that in eastern thought, esp Buddhism and Hinduism, it is taught that it is our very knowledge of good and evil (what they call the "opposites" of creation) that separates us from God.
"The Great Way is not difficult
for those not attached to preferences.
When neither love nor hate [re: the opposites] arises,
all is clear and undisguised.
Make the smallest distinction, however,
and heaven and earth are set infinitely apart.
If you wish to know the truth,
then hold to no opinions for or against anything.
To set up what you like against what you dislike
is the disease of the mind."
