What do you mean by that?
Since God's almighty by nature, He is almighty at any time. The only difference is whether you have seen it or not.
So, as a believer, we should believe in God's power. There's simply no such things that God's power was great at the creation of the world and is small at present.
Sorry that I didn't take it.
But anyway, as a devout believer, we should make no jokes about God. That's disrespecting God. It's something that comes from Satan. Because only Satan takes such an attitude towards God.
