Think for a second about the love your parents/grandparents have for you. Its an unending love to protect, adorn, serve. God has that same kind of love for all of us!
It's funny to think about God as a "parent". But I love how this verse puts it into perspective! We are the apple of the Lord's eye. Each and every one of us are, whether we are farmers, doctors or PETA supporters, God loves us all the same.
