What love has to do with it (knowing God)

In this message Pastor John will speaking about the idea that God is Love. If this is true, then is any experience of love and experience of God? And what does the nature of love teach us about who God is then?

"Everyone who loves has been born of God and knows God. Whoever does not love does not know God, because God is love"
1 John 4,7-8, NIV
