Love The 1 Cor 13 Way???

Three things under the Sun I understand not,
Four things that puzzle me,
The effect of alcohol on a drunk,
The power of love returned,
The effect of sleep on a man,
and the pain of the lack thereof of the above.

These seem to have the greatest power over man,
They will make him float,
Climb the highest mountain,
Achieve the loftiest goals,
Endure the greatest pains,
And be glad for meager gains.

But should he lack,
No rest shall he see,
No gain will be enough,
Until that state is changed,
That causes him to grieve.

They touch the body,
Affect the spirit,
And thrill the mind.

Oh that one could live without them!
You can if you have never known them...
Of them all of course,
The noblest is love,
Love, the Christ way.

But humanly can we love?
Can we love without expecting back?
Can we give endlessly and still be happy?
Is selfless a word we are comfortable with in our world?
Our idea of love is a romantic feel good emotion,
Based on being pleased, cared for as we do the same.
But what of that love that led Jesus to the cross?
That makes a mother go without to ensure her child has all?
That lets God stand us in our sin and not force us to love Him?

That is puzzling me today.
-
I want to love without expecting back,
To bless always, without condition,
To be happy without needing a reason,
To give without being asked....

Is that possible?
