Matthew 21:21 Jesus replied, ‘Truly I tell you, if you have faith and do not doubt, not only can you do what was done to the fig-tree, but also you can say to this mountain, “Go, throw yourself into the sea,” and it will be done.
We have many examples of Jesus saying something and it happens; miracles happening just because Jesus spoke the words...
We need to have the faith Jesus showed in God the Father; absolute, unending, unerring faith!
When we can believe with that much faith, Jesus says we can do amazing things, just as He did.
It is hard to have faith like that without seeing something first – because we are weak and don’t want to believe something just because it is written down...
