WHAT IS FAITH???

If today you just walk up to me & ask me to define faith I'll simply say it just believing the unseen. But back in the seminary we were taught that "faith is a special grace from God which enable us to believe without doubting what he can do" I've also encounter several definition from different people and writeups. Even if I ask you now you will give a different one all together. Thats the problem we cant get the best of our conversation if we define faith from different views thats why after comparing several definitions I realised they have in a way similarity with that of the us english dictionary "A feeling,conviction,or belief that something is true or real,without having evidence" which i suggest should be the primary view of our discussion here...If you think this definition isnt good enough you can as well suggest yours too .
