“He replied, 'Because you have so little faith. Truly I tell you, 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.’”
Do you know the size of a mustard seed? It’s usually around 1 to 2 millimeters in diameter, comparable to the tip of a pen. Essentially, it’s very small.
Mustard seed faith is a bit of an odd idea, but historically, mustard seeds were used as a figure of speech to indicate something minuscule. But shouldn’t our faith be large rather than small? Why would Jesus want us to have faith the size of a mustard seed—minuscule faith?
