How do you know that you know God?

Hereby we know that we know Him - IF WE KEEP HIS COMMANDS because he who says "I know Him" and does NOT keep His commands, is a LIAR and the truth is NOT in Him but if we keep His Word, hereby the love of God is perfected in us and we know that are IN HIM   (1 John 2: 3-5)

You start off with the premise that God exists and is indeed, knowable. Then, you embark upon a regular, personal program of religious study and prayer, coupled with a lifetime of full, faithful participation in all the work, worship, sacraments and devotions of the Holy Catholic Church. Works every time!

Peace is the perfume of God. When God is close to you, you smell this perfume. And this perfume is exquisite. It is beautiful. 

The senses dance, and life in that moment becomes complete. 

This beautiful aroma, this beautiful perfume,

is what this heart desires — again and again and again. 

- Prem Rawat

NO valid study shows that, Barf. Intuitions can prove nothing. They can only help form a hypothesis. Math, morality, etc. are HARDLY intuitions. You obviously never had an advanced math course if you don't know how to prove the square root of 2. You don't even know what an intuition is.

Prove that God exists or stfu, douche bag.

You can only 'know' a god critter by pretending.

My intuitions tell me so. Studies have shown that people are born with the intuition that God exists. This is a consensus in cognitive science and psychology. 

According to atheists, our intuitions can’t be trusted since they’re just the byproducts of blind evolution. But that would also mean that none our intuitions can be trusted, including intuitions about logic, math, counting, morality etc. 

I don't because I don't imagine one exists.

One has to imagine a god exists before imagining that they know it.
