some one had their heart set on the fancy cars

because the story was set in the 1600's and was writen in the 1800's belive it or not

My Heart Is Set on You was created in 1990.

This answer is more of a personal answer but I you out.

To set your heart on God would be best understood if you knew what

"heart" meant.

Your heart is you, the depth of your being.

To set your heart on God to me would mean to "set the focus of your

existance on who God is".

God Bless

It means they like you and no one else
