Spurgeon and mystery

Rebecca Writes: is doing Spurgeon quote month and has the following from the prince of preachers:

“How is it that the Father is God, that the Son is God, and that the Holy Ghost is God, and yet that there are not three Gods, but one God? I cannot tell you. I know it is so, for it is revealed; but how it is so is not for us to guess, because it is not revealed or explained. Our understanding can adventure as far as the testimony, and no farther. Many attempts have been made by divines to find parallels in Nature to the Unity and the Trinity of God, but they all seem to me to fail.”

This seems to me to be relevant to our discussions about the atonement- how the mystery of the trinity relates to the mystery of the cross is beyond me. How can God the father and son be both united in love and yet divided by wrath against sin at the same moment is beyond me but the bible plainly teaches it is so.
