I have sometimes struggled to understand how God operates. But is it really possible to fully understand God? No it is not. In Isaiah 55:8-11, He says his ways are higher than our ways and his thoughts higher than our thoughts. We can't understand why God allowed Lucifer to live on. We don't understand why God would let children be killed and not intervene, we don't even understand when God says in His commandments not to do certain things. Instead of trying to understand first before we obey or acknowledge his works, we should instead have faith in his supreme authority. It's called unwavering faith. Be blessed.
