It is incredible how many scriptures can be found on "faith" and sometimes it just has to hit you in the head that it takes faith to receive what you have been promised, even if you can not see it nor feel it.  Just a few scriptures on Faith that is helping me.

14:31 And immediately Jesus stretched forth [his] hand, and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt?

17:20 And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.

4:40 And he said unto them, Why are ye so fearful? how is it that ye have no faith?

11:22 And Jesus answering saith unto them, Have faith in God.

11:1 Now faith is the substance of things hoped for, the evidence of things not seen.
