With Hashem running the entire world and everything with a plan and accounting for. Anything is possible for Hashem to do with a flip of a finger with his malachim and sending them to do anything like Hashem sent Malach Gavriel to destroy the entire army of Sancheiriv and the way it was done by having the chayos sing the holy spirit song of praise to Hashem it removed their souls from their bodies and they were all immediately dead with no war at all to kill such a large army.
If we start to put our COMPLETE FAITH AND TRUST IN HASHEM then Hashem will take care of all our needs as we say in bentching from Tehillim chapter 34 Vdorshei Hashem…. Which means for one who seeks out Hashem directly-not through messengers like rebbas or segulahs etc….-lacks nothing that is good.
