What does the line “Swear to God I’m a sinner in a church burning up for you” mean in this song?

Song: Girls like you by Blackbear
Lyrics:
give me your forever, or at least just for a while
give me never ending, or at least give me a mile
give me happiness, or at least give me a smile
give me forever for a while, give me forever for a while
quit actin’ like a baby, or at least less like a child
give me serenity, or at least just peace of mind
give me closure, or at least a phone call
give me forever for a while, give me forever for a while
swear to god i’m a sinner in a church, burnin’ up for you
swear to god she’s a blessing and a curse, shoulda learned from you
swear to god i’m a sinner in a church, burnin’ up in flames
swear to god, shoulda learned, shoulda learned
to never, never, never
Give me your forever

I'm sure the tune is pretty cool but the lyrics suck. I like the first part about the mile smile the give me your love for a while but that song is kind of wrong and it's discourse because it should be forever on all of the above not just for a while but forever

I guess it means the person would do anything for love and that means being a sinner and burning in hell for true love. That is the way I interpreted the lyrics.

I think it means that the person is basically doin all the wrong things just for the person they singin to be with them forever or give them their live forever..

My brain deserves better than to try to understand today's crap music. Sorry.
