The answer to this question depends entirely on your definition of God. See there are two main ways that people tend to view 'god.' A transcendent god is the traditionally western view of god, this god exists outside this reality. He created this world but he is above it. In this view people must 'purify' themselves to form a worthwhile relationship with god.
The traditionally eastern view of god is an imminent god. This god exists within this realm, he embodies it and everything within it. He is you, he is nature, he is air and fire and earth. In this view it is utterly useless to deny yourself of life's rich experiences. Because all that is god is sacred and you are a part of this, you are sacred.
Through the first view, love through god is something that needs to be obtained...and through the second view love through god is something inherent.
I tend to reject the idea that love is something that must be 'obtained' but strict Christians may say that once you purify your love (through god) then it is experienced in a new way.
Through the second view, love is to be embraced in all it's forms as divine and sorrow is to be embraced the same way. These experiences are part of you and you are part of god and so all of that is divine.
One long complicated answer later...I'm going to just say this question is akin to the question of how we relate to god...and in my personal view there is a third option.
In an integral approach one would try and mend these opposite ideas. Love (as a strong element of human emotion) resonates on a divine level. As you put your(physical)self into accord with your spiritual and divine SELF...the love will resonate more deeply.
