All you need is love

What do you believe about love?

I believe I have a responsibility to love in an active and social and global way. It is a call of my faith, and a deep truth that resonates within me. Love needs to be the foundation, the reason, the spring from which all my other activities flow. It's like this:
If I speak in the tongues of men and angels, but have not love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but have not love, I am nothing. If I give all I possess to the poor and surrender my body to the flames, but have not love, I gain nothing.
1 Corinthians 13:1-3

But love is not just an action and a motivation. It is a resting place. It's like this:
When in disgrace with fortune and men's eyes,
I all alone beweep my outcast state,
And trouble deaf Heaven with my bootless cries,
And look upon myself and curse my fate,
Wishing me like to one more rich in hope,
Featur'd like him, like him with friends possess'd,
Desiring this man's art and that man's scope,
With what I most enjoy contented least:
Yet in these thoughts myself almost despising,
Hap'ly I think on thee - and then my state
(Like to the lark at break of day arising
From sullen earth) sings hymns at heaven's gate;
For thy sweet love remember'd such wealth brings
That then I scorn to change my state with kings.
- William Shakespeare, Sonnet 29

And love has the power to change everything. It's like this:
Love makes your soul crawl out from its hiding place.
- Zora Neale Hurston

Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate, only love can do that.
- Martin Luther King, Jr.

It's Valentine's Day. What do you believe about love?
