The cover art for the promotional single was created by the illustrator Aurore Hutton, niece of former French President Valéry Giscard d'Estaing.

[3] The song was written by Marie Bastide and Gioacchino Maurici, while the production was handled by Jacques Veneruso and Patrick Hampartzoumian, who also produced Dion's previous single, "Parler à mon père".

[8] Alain de Repentigny from La Presse wrote that it is a catchy pop song that we can hum from the very first listen, but whose charm wears out quickly.

[10] Marty Tobin of Quai Baco got the impression that he heard the melody of "Le miracle" dozens of times since Joe Dassin, but the presence of the choir and "Celine's touch" make it work well again.

[18] Vergnes previously worked with Dion in 2007 on her videos for "Et s'il n'en restait qu'une (je serais celle-là)" and "Immensité," and in 2012 on "Parler à mon père".

[20] It was shot under the autumn sun with Dion walking among the trees with orange and red leaves, while several people jump in the air to express their joy and happiness.

[26] "Le miracle" was the closing number to her Céline... une seule fois concert held in the Plains of Abraham in Quebec City on 27 July 2013, and one of the closing songs to her concert at the Sportpaleis in Antwerp on 21 November 2013 during the Sans attendre Tour; the former was included in the Céline une seule fois / Live 2013 CD/DVD.
