Matthew 21:20-22

20 Seeing this, the disciples were amazed and asked, "How did the fig tree wither all at once?"

21 And Jesus answered and said to them, "Truly I say to you, if you have faith and do not doubt, you will not only do what was done to the fig tree, but even if you say to this mountain, 'Be taken up and cast into the sea,' it will happen.

22 "And all things you ask in prayer, believing, you will receive."

Luke 11:9-10

9 "So I say to you, ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you.

10 "For everyone who asks, receives; and he who seeks, finds; and to him who knocks, it will be opened.

John 16:23-24

23 "In that day you will not question Me about anything. Truly, truly, I say to you, if you ask the Father for anything in My name, He will give it to you.

24 "Until now you have asked for nothing in My name; ask and you will receive, so that your joy may be made full.

1 John 5:14-15
