Is it possible to wholly love someone that you don’t truly know?

Mark Schmidt spoke from Philippians 3: 10 - 12

¹⁰ I want to know Christ—yes, to know the power of his resurrection and participation in his sufferings, becoming like him in his death, ¹¹ and so, somehow, attaining to the resurrection from the dead. ¹² Not that I have already obtained all this, or have already arrived at my goal, but I press on to take hold of that for which Christ Jesus took hold of me.
