"Isn't It Wonderful?" is an affirmation technique by Neville Goddard. Assume that what you wished for is already come to pass and feel how wonderful it is!
Here are some affirmations I wrote inspired by this:
Isn’t It Wonderful? All your wishes have come true.
Isn’t It marvelous? You have nothing to worry about now.
Isn’t It so awesome? You are so happy and satisfied right now.
Right now. Isn’t It lovely? There is nothing more you need now. You have all the abundance you ever wanted.
Isn’t It beautiful? You have your true love right next to you.
Isn’t It so wonderful? You have perfect health and a beautiful functioning body.
Isn’t It so perfect? Something Marvelous is happening to you.
Right Now.
Right now.
You are over the moon right now that all of your wishes are fulfilled and You are living in the end.
