Sometimes I need to be alone
Kendrick humbly acknowledges that he is a human who makes mistakes. The skit leading into this song is his father wanting to listen to his complaining Kendrick/his mother are “killin' [his] muthafuckin' vibe.” His dad might use drinking and listening to music as a means of escape from this life.
Others believe to sin is to doubt of god. So, because Kendrick don’t understand some things, he acts sinfully and doubts god.
This might be Kendrick’s prayer and confession, for the lack of understanding that misguides him.
