“‘Truly!
I say to you!
If you say
To this mountain.
‘Be taken up!
Be thrown
Into the sea!’
If you do not doubt
In your heart,
But believe
What you say
It will come to pass,
It will be done
For you.’”
ἀμὴν λέγω ὑμῖν ὅτι ὃς ἂν εἴπῃ τῷ ὄρει τούτῳ Ἄρθητι καὶ βλήθητι εἰς τὴν θάλασσαν, καὶ μὴ διακριθῇ ἐν τῇ καρδίᾳ αὐτοῦ ἀλλὰ πιστεύῃ ὅτι ὃ λαλεῖ γίνεται, ἔσται αὐτῷ.
This Jesus saying about faith can be found in Matthew, chapter 21:21, somewhat similar to this in Mark. Mark said that Jesus answered with a solemn pronouncement (ἀμὴν λέγω ὑμῖν) about the importance of faith. If they had faith, they could move mountains. They could tell a mountain (ὅτι ὃς ἂν εἴπῃ τῷ ὄρει τούτῳ) to be lifted up or taken away (Ἄρθητι) and thrown into the sea (καὶ βλήθητι εἰς τὴν θάλασσαν). If they did not doubt it in their hearts (καὶ μὴ διακριθῇ ἐν τῇ καρδίᾳ αὐτοῦ), but believed what they said (ἀλλὰ πιστεύῃ ὅτι ὃ λαλεῖ γίνεται), it would happen or take place or come to pass for them (ἔσται αὐτῷ).
