Did they not pray hard enough this time?

Not dice, no.

In all seriousness, if you prayed for Trump to win and Biden won, how do you rationalize that? If you say Trump ‘actually won,’ but ‘evil forces’ are blocking the victory, isn’t God omnipotent, omniscient, and omnipresent?

Were your prayers not answered because you didn’t pray hard enough? Did God ignore them? Did some other force impede God’s will? Is it possible that Biden’s victory was God’s will?
I am asking these questions honestly. No snark. I am trying to understand the thought process of a segment of society.

Anything they like = God’s plan

Anything they don’t like = God’s punishment of a sinful society

Yeah, it doesn’t make sense. But that’s their thought process if you take them at their word.

God is punishing us for not murdering all the gays.

I'm not Christian so I can't answer to the thought process of Christians. But the Bible says you should not ask God for things and then be disappointed if you don't get them. "Do not put the Lord your God to the test" Deuteronomy 6:16. People I have heard talk about this subject say you should pray for the strength to accomplish a task or endure a hardship, but not pray that the task is accomplished as you wanted.

If you believe God is omnipotent, then you would have to believe there was a greater purpose to the election that God understands and is not apparent. "Who can fathom the Spirit of the Lord, or instruct the Lord as his counselor?" Isaiah 40:13.

Like I said I'm not Christian. If you want to know what Christians think you could ask in a Christian stream and not this stream full of godless heathens.

No we are deifying god to them.
