Isaiah says “That your maker is your husband” (or tender partner). He is all-powerful, always available and is therefore above human frailty. He provides so much more than ever a human husband/wife can. Human support is often good, but it sometimes hinders our spiritual growth. If we are turning to a material personality all the time, we might be let down. And there is a wonderful promise in Isaiah 54, look it up. And you will find more views of goodness and divine Love.

“Would existence without personal friends be to you a blank? Then the time will come when you will be solitary, left without sympathy; but this seeming vacuum is already filled with divine Love. When this hour of development comes, even if you cling to a sense of personal joys, spiritual Love will force you to accept what best promotes your growth. Friends will betray and enemies will slander, until the lesson is sufficient to exalt you; for “man's extremity is God's opportunity.” The author has experienced the foregoing prophecy and its blessings. Thus He teaches mortals to lay down their fleshliness and gain spirituality. This is done through self-abnegation. Universal Love is the divine way in Christian Science.
