What does faith mean? To understand this, first we need to understand what does doubt mean. What is the source of our doubts and what do we really doubt?

Understand that which withstands all doubts is faith.

Our doubt is always about something that is POSITIVE.

You doubt the love of somebody, not the hate of anyone.

You doubt the honesty of somebody, you never doubt the dishonesty of someone.

You doubt your happiness, you never doubt your depression. Have you ever doubted your  depression? That means, have you ever said, ‘Wait, let me see, am I depressed or not’. We have always sure of these negative things in life!

Realize that this is the nature of doubt. And faith is that something which even doubt cannot overshadow.
