It is saying that there does appear to be a real contraction between God’s love and his power to act to stop suffering. But that there are limits to human understanding and that God has infinite wisdom and insight that we cannot ourselves grasp.
I used that reasoning about 15+ years ago. I got no relief until understood that the Bible is all mythology and best not be taken literal. Psychological speaking the Bible is important because it furnishes understanding of the minds inner workings and what we projected on to the unknown. I would suggest read some of Carl G Jung's works on bible themes.
