It's just now dawning on me

that Musiq was talking to love as an abstract idea here, not love as a person he loved. 

So in that vein, I have to agree with him:

"(Love) So many people use your name in vain [ain't that the truth?] / (Love) Those who have faith in you sometimes go astray [I don't want to be one of them again]/ (Love) Through all the ups and downs, the joys and hurts/ (Love) For better or worse I still will choose you first."
