[move] mountains
1
to accomplish something challenging or seemingly impossible through extraordinary effort and determination
The origin of this idiom comes from the biblical story of Jesus, where he says, "If you have faith as small as a mustard seed, you can say to this mountain, 'Move from here to there,' and it will move. Nothing will be impossible for you." The phrase "move mountains" has since been used to describe any situation where a seemingly impossible task is accomplished through extraordinary effort.
