Mark 11:20-24

20In the morning, as they were passing by, the disciples saw that the fig tree had withered away from the roots up.

21And remembering, Peter said to Him, “Rabbi (Master), look! The fig tree which You cursed has withered!”

22Jesus replied, “Have faith in God [constantly].

23I assure you and most solemnly say to you, whoever says to this mountain, ‘Be lifted up and thrown into the sea!’ and does not doubt in his heart [in God’s unlimited power], but believes that what he says is going to take place, it will be done for him [in accordance with God’s will].

24For this reason I am telling you, whatever things you ask for in prayer [in accordance with God’s will], believe [with confident trust] that you have received them, and they will be given to you.
