Faith is something we believe in. Like, "l believe in ghost" or l believe my birthday is coming in 12 days" etc. Having a Christian faith can be a bit of a challenge because:
We don't want to trust in something we can't see
We want to follow our own paths
We don't want to follow HimIt is not easy having faith in a God that you can not see and what you have to go by off of the BIble but it's something more than that. Putting faith in Him is your choice. You get the choice to follow Him and listen to Him because He is letting you make that decision. God loves you and He cares for you.
