Is God Almighty omnipotent?

Hey Miki
Hello, I've reached a point where my stomach is bothering me and I can no longer help but bother you with a question that I may have already asked before, in a different way.
At the beginning of our dialogue, I presented to you my argument that, as I understand it, God is not omnipotent. Later, I refined this argument into another version, which is that God cannot, for example, produce an earthquake from one moment to the next, but God can time events so that an earthquake will ultimately help to realize God's plan.
It later occurred to me that defining God as "merciful and gracious" is especially challenging in light of the fact that God allows horrors to occur in our world, horrors in which tender children are tormented in hellish agony until death redeems them from their torment. And prayers go unanswered.
To the best of my knowledge, there is no explicit statement in the entire Bible about God being omnipotent. Someone in my group quoted a verse [I think it's from the book of Hosea], from which we can conclude that God is omnipotent. But I think that based on the fact that there is no explicit statement in the Torah about God's omnipotence, it seems to me that from a theological perspective it is better to assume that God is not omnipotent than to assume that the explicit statement about God being merciful and gracious is not true!
I would be very grateful if you would address this claim of mine.
