A girl loves her doll. If someone wants to borrow it, she will not let go
of it. If she sees the same doll in a store, she doesn't pay any attention to
it.
When she grows older and finds a human lover, she abandons the doll. When
she finally finds and loves God, she abandons the changeable human lover just
as she did with the doll.
God's love is unchanging and eternal.
