In my view, when the bible talks about Satan controlling this world, it means that the people attracted to power are the ones of lower moral standards. When I explain this to my kids, what I say is that "power is for the one willing to stoop lowest to grab it". There are a lot of reasons for that, partially because that is their punishment, since they get to deal with all the bullshit and having to live knowing they may get whacked. Part of it is that if you have a highly moral weakling running the show, it doesn't turn out well.

At the end of the day, of zelensky, putin and biden... well jesus may say they deserve your prayers and maybe they do. I would say that the average Ukrainian and Russian caught up in this nonsense certainly do, so pray for them if you struggle with praying for the Ukraine.

As for the bowls and theology and stuff like that, well they certainly talk about it in revelations. Yet I'm probably not what most Christians would call a Christian so my interpretation would probably differ from those in your church group. I can say that analogies and symbolism is often used to communicate in the bible however.
