This evening I watched the music video for for Justin Bieber's song "Pray" for the first time. 
Wow!
This is the quality that makes him more that a teen pop star. With striking images of children in poverty and sick in the hospital, it's easy to get emotional. The song hits your heart cords of hope. Hope for a better tomorrow through envisioning right livelihood for all. Which arises from your wiliness to show up for others in any small way to  create change. As this is what Justin is shown doing when he visits the children in the hospital and to make a wish participants, bringing them smiles and putting them in high spirits. 

Speaking of spirit, there is another layer of spiritual significance to this song, if you look closely. 
Justin's song "Pray" runs 3:33 minutes long. 
According to Doreen Virtue's Spirit Numbers, the spiritual significance of 333 is as follows. 

333 - The Ascended Masters are near you, desiring you to know that you have their help, love, and companionship. Call upon the Ascended Masters often, especially when you see the number 3 patterns around you. Some of the more famous Ascended Masters include: Jesus, Moses, Mary, Quan Yin, and Yogananda.
I hope, pray, and know that Justin will continue to sing songs like this well into his career.
