[BIBLE]Matthew 17:20[/BIBLE] I've heard explanations of the "moving mountains" passages. For the most part, they involve the believer knowing the will of God (through prayer, study, and fellowship) well enough to know that moving mountains is his will. I listened to a Redeemer PCA sermon linking it to Zechariah's prophecy that God will split the Mount of Olives in two. I kind of get all that -- in other words, the point is not that we have to believe, and then whatever we ask will be granted, but rather that whatever we ask in his name will be granted but we first need to know what things can be asked in his name. That all is background for my actual question. Those explanations seem to make sense for every "mustard seed" and "moving mountains" saying of Jesus, except for this one. I can't see why the amount of faith would have any bearing on their request being granted or not being granted. So basically my question is, in what sense do the disciples have "too little" faith?
