faith precedes the miracle

The more I look into this topic the more I go back to the beginning...belief...belief that things will happen; belief Father in Heaven loves us; belief that there are no limits to his powers...and if I do not ask amiss (2 Nephi 4:35) it shall be granted. Now, here is where it can get a little confusing...belief is not the same as having faith...or is it? We are ask to belief 100% that things will happen but all we need is faith as a grain of mustard seed (Mat 17:20) to move mountains...
