Beyond the mystical, for me is upmost respect, even when I thought I was agnostic I always respected Him, but not for what He said, but for what He did. All His actions led him towards the cross.

Here is a good translation of a XVI century Spanish poem from an anonymous author, original title "No me mueve mi Dios para quererte"

The author just like Descartes' Meditations, searches for reality as foundation, in his/her case, is not mathematics, but staring to His body at the cross:

"I am not moved, my God, to love you

By the heaven which you've promised.

Nor am I moved by the Hell I fear,

And for that reason, not to offend you.

You move me, Lord! It moves me to see you

Humiliated and nailed to a cross;

It moves me to see your body wounded so;

It moves me to behold your suffering and death.

Ultimately, I am moved by your love,

In such a way that even if there were no heaven, I would love you,

And even if there were no hell, I would fear you.

You need give me nothing for me to love you,

For even if I had no hope for things hoped for,

I would love you the same as I love you now."
