Jesus' faith in me

I recently saw a movie named Constantine and there was a conversation from this film that has been sticking with me for the last couple of weeks. THe conversation goes with Constantine saying to the lead woman, I forgot her name, saying, "Do you believe in the Devil?" And she replies," No." His answer to her is," You should; because he believes in you." This short conversation has been in the back of my mind for some time now and I have decided to switch in Jesus for the Devil and wonder how much Jesus believes in me and how much I should believe in him? The answer to this is a lot because Jesus is the one that gave me the faith to believe in him in the first place.
