Biblically speaking, Christians are taught to "Call those things that be not as though they were." (Romans 4:16-22).
As an example, Abraham was about a hundred years old, and stood fast in his faith that God was faithful. He believed his wife, far beyond child-bearing years, would bear him a child. Because he never wavered in his faith that God is faithful to fulfill His Promises, God granted them Isaac.
Sadly, Christians are blurring God's Word with something called "The Secret". God does not keep His Word a secret. It is an open book for all, on how to please Him.
On the other hand, satan likes to perpetrate things in secrecy; because they always make God seem irrelevant. That's what those who promote "The Secret" are guilty of doing. Many have gotten rich promoting this 'name it and claim it' falsehood. It's one thing if God puts a faith seed in your spirit; and, a whole other to say....oooo there's my this...there's my that...smh...rme...
Long story short, I agree that we can focus on the truth that in all things God works life out for His Glory and the good of all who are called (Romans 8:26).
He admonishes that when He gives one a vision, a Promise in the spirit, it should be believed for; the person should believe for it/wait for it, til his last breath if necessary. (Habakkuk 2:3).
Peace.
