Hebrews 11:6 And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him.what is faith? simply believing what God has said in his word. we have problems believing for big things. because we have little faith. how do increase your faith? faith is like an ability, which grows through experience, practice, commitment and sacrifice. like building muscles. it grows when we survive victories and defeats. its not like the flu, but i do think being around faith filled people it will give you hope.
when you need faith to trust God for big things, fasting is a great way to develop it.
when you fast and pray , you should expect miracles to follow.

Isaiah 58:6-8 (New King James Version)
6 “ Is this not the fast that I have chosen:
To loose the bonds of wickedness,
To undo the heavy burdens,
To let the oppressed go free,
And that you break every yoke?
7 Is it not to share your bread with the hungry,
And that you bring to your house the poor who are cast out;
When you see the naked, that you cover him,
And not hide yourself from your own flesh?
8 Then your light shall break forth like the morning,
Your healing shall spring forth speedily,
And your righteousness shall go before you;
The glory of the LORD shall be your rear guard.
