Mat Matthew, chapter The Gospel According to Matthew, chapter 21
Jesus taught the disciples a lesson from what happened to a fig tree.
Matthew 21:18-22
Jesus said to us, “Think about this: If you believe that God has power to do what you ask him to and you do not doubt that, you will be able to do things like what I have done to this fig tree. You will even be able to do marvelous deeds like saying to a nearby hill, ‘Uproot yourself and throw yourself into the sea’, and it will happen! Mat 17:20; Luk 17:6; Jas 1:6
