Question

how do we know or feel that god exists

Answer 1

Although our feelings tell us that at times, we shouldn't be driven by our emotions when it comes to our trust in God. Because Scripture says the "righteous shall live by faith" (Romans 1:17)  and "without faith it is impossible to please God" (Hebrews 11:6), we shouldn't have to feel God to know He's there. But I know how you feel if you find yourself discouraged at times because it seems like God just isn't around.  

Answer 2

We can not see air but we know that air is present all around us.
By feeling it.
Like that only by feeling the presence of God all around us.
