One would expect that if an omniscient God needed or wanted to get his creation's attention, he would devise a way so ingenious that it would immediately poduce the intended result. I'm currently not giving any special thought to an hypothetical deity nor do I believe there is such a deity in the first place. If this is a divine device to catch the attention of all his creation, either I'm not part of this creation or this deity failed and thus isn't omniscient.
Everyone supposes the creator to be a 'deity'. The concept of deity is ancient and primitive. God is not a deity. God is the ever living consciousness that created what is. "God" is love. The source of all life. God does not require worship, which too is a concept that ancient people created to venerate any personification of the forces of nature and its phenomena. Phenomena which were mysterious and often fearful. Seasonal change, drought, earthquakes, fire,etc. This is clearly illustrated in the story of the Hebrews who attributed the ten plagues to their deity.
"God", the Hebrew concept that was merged with the Christian concept, was worshipped no differently than the pagan gods and the idea of the singular god of the Hebrews was as to character no different than the multitude of pagan gods. Christians followed through with their concept of worship of "God" in similar manner as the pagans and attributed every possible consequence of life on earth to their deity's whim. Today, despite advances in scientific knowledge about the physical world what is supposed to be mysterious, and unexplainable is attributed to God. Hence all the questions about 'why Covid-19). The same behavior and belief patterns persist among human beings today because they do not recognize what God really is, and because they continue to suppose that God is a jealous and judgmental dictator, or 'deity' whose authority is not to be questioned without consequence.
But if you understand that what is called "God" is love, alive, conscious and benevolent, you can follow with simple questions like "What does love do? What doesn't love do? What is love like and what is love not like." The answers to these simple questions will tell you that is indeed God is love. God does what love does. Love does not condemn or curse, or do violence, or wish violence. Love does not wish for those who are loved to suffer from an attitude of vengeance or punishment. In short people who look at "God" from the traditional religious perspective never can understand God, and live in fear of God always, because they do not see God as love, but rather as 'deity'. Deity is equated with 'authority', in this case 'divine authority', hence god is also called a "king" who sits on a throne. Another human concept. Humanity understands 'authority' in a ways that do not accord with love. Hence, 'divine authority' is equated with human notions of justice and punishment, judgment and in kind rewards, such as you see in the old testament Bible commandment, "an eye for an eye". The God of love could not have given such a law since love is about forgiveness and healing, not the perpetuation of pain and suffering. These are human concepts that stem from human prejudices and fears, un-forgiveness, vengeance, war, hatred, and punishment. This too is clearly seen in the justice systems of the US, where people are punished and even killed in the name of 'justice'--and eye for an eye. Christian claims of forgiveness along those lines are false, since Christians demand 'justice', judgment and punishment from both the authorities man and as they claim and call authority in the name of God. Love does none of these things. But it is not a stretch that authoritative 'deitys' do. This warped thinking naturally supposes that God is doing judgment over humanity when diseases and other large scale trouble comes to human beings. But god is no more responsible for Covid than people are responsible for the heat coming from the sun.
