I am a sinner who's probably gonna sin again
Lord forgive me, Lord forgive me
Things I don't understand
Sometimes I need to be alone
from Kendrick Lamar – Bitch, Don't Kill My Vibe Lyrics on Rap Genius
A major theme in Kendrick’s music in general is his faith and how he reconciles it with the sinful activities that enjoys)

Kendrick begins this song by humbly stating he is a human that makes mistakes. The lead-in for this song is Kendrick’s father saying “matter of fact, cut my muthafuckin' oldies back on. You killin' my muthafuckin' vibe.” This whole first verse could be about Kendrick or his dad and their tendency to drink and listen to music by themselves as a means of escape.
Another interpretation is that it´s a sin to doubt of god. So, because Kendrick don´t understand some things, he doubts god, which is a sin, and because of this he asks for forgiveness.
Yet another interpretation is that would seem that Kendrick is being more antichrist with the lines “Lord forgive me. Lord forgive me: things I don’t understand”, Therefore, Kendrick is poetically saying that “Lord forgive me. Lord forgive me”, which insinuates prayer and confession, are “Things (he) (doesn’t) understand.” Because “(He) (is) a sinner who’s probably gonna sin again.”
