When feeling out of sight

How do I love thee? Let me count the ways.
I love thee to the depth and breadth and height
My soul can reach, when feeling out of sight
For the ends of Being and ideal Grace,
I love thee to the level of everyday's
Most quiet need, by sun and candle light.
I love thee freely, as men strive for Right;
I love thee purely, as they turn from Praise.
I love thee with the passion put to use
In my old griefs, and with my childhood's faith.
I love thee with a love I seemed to lose
With my lost saints,-I love thee with the breath,
Smiles, tears, of all my life!-and, if God choose,
I shall but love thee better after death.

Hi,

The above is the Sonnet 43 by Elizabeth Barret Browning. I have problems interpreting the bolded parts. I'd render them into the following. Correct me if I am wrong. Thanks.

1. When I feel I can't see the ends of our lives and God's perfect Grace. I love you to the degree of daily most basic need day and night.

2. I love you with a love that I seemed to no longer have; this love has gone with my lost angels.

3. If God permit, I shall only love you better after we both pass away.
