是加拿大流男歌手Justin Bieber演唱的歌曲，收录在其同名专辑中。专辑标准版唱片共收录13首歌曲，日版唱片多收录5首歌曲，豪华版唱片则收录18首歌曲。三版唱片于2015年11月13日通过小岛唱片发行。
作为首次转型，存在缺憾是正常。《Purpose》当然无法比肩诸多经典专辑，它依然没有彻底消除奶味，尽管制作强大也无法解决质感单薄问题。但对于歌手本人而言，这已算是最巅峰表现。专辑的终极意义是打造新增长点，歌手发展路线进入新阶段。这意味着，在将来，贾斯汀•比伯除了继续带来更多麻烦之外，还能够带来更精彩的专业表现。

Purpose歌词：
Feeling like I'm breathing my last breath
Feeling like I'm walking my last steps
Look at all of these tears I've wept
Look at all the promises that I've kept
I put my heart into your hands
Here's my soul to keep
I let you in with all that I can
You're not hard to reach
And you bless me with the best gift
That I've ever known
You give me purpose
Yeah you've given me purpose
Thinking my journey's come to an end
Sending out a farewell to my friends for inner peace
Ask you to forgive me for my sins oh would you please
I'm more than grateful for the time we spent my spirit's at ease
I put my heart into your hands
Learn the lessons you teach
No matter what wherever I am
You're not hard to reach
And you've given me the best gift
That I've ever known
You give me purpose everyday
You give me purpose in every way
Oh you are my everything
Oh you are my everything
