“Then Jesus answered and said unto her, O woman, great is thy faith: be it unto thee even as thou wilt…”  
Matthew 15:28

Wow! With great faith, everything would be unto you the way you will- it is what you will that would come to fruition! Remarkable.
See that in the main verse, Jesus qualifies faith, he told this woman she had great faith.
“…according as God hath dealt to every man the measure of faith.”  Romans 12:3
Every Christian has faith; it took faith to believe the gospel. As the word of the gospel was being announced to you, that word imparted faith into your spirit and with that faith, you got born again.
Every Christian has exactly the same kind of faith with the Apostles:
“This letter is from Simeon Peter… I am writing to those who have been given a faith as equally precious as ours…”  2Peter 1:1, TPT
And with Jesus:
““…My new life is empowered by the faith of the Son of God…”  Galatians 2:20
Same kind, but different in size and tensile nature. So you have Christians who just live their lives based on what is thrown at them by the world, while you have Christians who not only have all they need, they get what they want:
“The LORD is my shepherd; I shall not want.”  Psalm 23:1
“The Lord is my best friend and my shepherd. I always have more than enough.”  Psalm 23:1, TPT
Great faith! That’s what you should express, that’s the answer to all you requests manifesting for you!
