Pray for you

Could I ask a question about the song "Pray for You," please?
What does "take the high road " mean?
Thank you so much.

Part of "Pray for you" lyrics:
I haven't been to church since I don't remember when
Things were going great til they fell apart again
So I listened to the preacher as he told me what to do
He said you can't go hatin' others who have done wrong to you Sometimes we get angry but we must not condemn
 Let the good Lord do his job, you just pray for them
I pray your brakes go out runnin' down a hill
 I pray a flower pot falls from a window sill
And knocks you in the head like I'd like to
 I pray your birthday comes and nobody calls
 I pray you're flyin' high when your engine stalls
I pray all your dreams never come true
Just know wherever you are, honey, I pray for you
I'm really glad I found my way to church
Cause I'm already feelin' better and I thank God for the words Yeah, I'm gonna take the high road and do what the preacher told me to do
You keep messin' up, and I'll keep prayin' for you
