If we look at brothers from the side, we can see distance between them, but when their father looks down on them from above, they are the same. God invests absolutely, eternally and unchangeably, so He is absolute, eternal and unchangeable. To know God is to know me. The omniscient and omnipotent God also is distressed over something He can't do because of His parental heart. The parental heart desires for brothers to love each other as parents love them.
Parents can be joyful or sorrowful by one word from their children.
One who has a longing heart is not lonely, because he has hope. There is no difference between men and women in the vertical love. For example, the same parental love goes to both the son and daughter. God loves the man who loves the Creation which God loves. The vertical God couldn't have a direct connection to the horizontal relationship between Adam and Eve.
