What do you need first when you are doing something new? For me, that would be believe because you need to believe on everything to make that possible. If you do not believe in that, then you do not believe in anything.
You need to believe in the God. The God has to be believed or else they would not make any sense to believe in something that you do not believe in.
You have to believe in everything that you want to make it happen. If you don't believe the person who gives the lottery, then you would not even buy the lottery. That would make the lottery not to come to your possession. That would make you lose more of the believe.
So the ultimate message, believe in yourself and believe in the God.
