It's true that God decides when we die, and death for a Christian means we go to a much better place....
BUT...
There are things I want to do in this life on this earth. As glorious as Heaven is bound to be, I'm not in a hurry for God to call me home.
Which brings us to timing. That God decides when we die, doesn't mean that we can't influence his timing. The timing is not necessarily set in stone and immutable, no matter what we do.
Otherwise, you'd think suicide victims have an incredible sense of timing to off themselves just when the Lord was going to call them home anyway.
So speaking of suicide.... There's a Christian in my office who believes like some Freepers, that we shouldn't be at all concerned about Covid. That our lives are in God's hands and Covid is of no effect. That same Christian missed 2 weeks of work when Covid knocked him down. But he did recover.
I take a slightly different view. If I stand on railroad tracks and see a train coming. There must be at least 1000 ways that God can save me. He can have wind blow me off the tracks, or a wild animal attack and drag me off the tracks. He can transmute my body and allow the train to pass right through me, the way Jesus passed through locked walls in His resurrected body. He could allow the train to hit me, and yet I walk away unscathed. Or he could have doctors put me back together through countless miracles.
But I think, God gave me a brain. And that God given brain is telling me, "Hey Danny! There's a train coming. Get your butt off the tracks!! NOW!!!".
Now if I ignore that God given brain, then God can still save me from the train. But all bets are off. If I'm stupid enough to ignore the brain that God gave me, then who knows what God will do. He might save me despite my stupidity. Or he may facepalm and tell the angels to get my spot in Heaven ready.
Now if God had said to me, "Stand in the way of this train", that would be different. My brain would then have to decide am I going to trust my Creator. Or am I going to trust in my own limited understanding. I'd like to think I'd trust my Creator. I really hope my faith never gets tested that way.
David took on Goliath. And scripture doesn't say that God told David to. But David knew he had been ordained by God to be the future king. He also knew it wasn't God's desire for God's people to be defeated by the Philistines. So David had faith that God would bring a victory in David's favor.
Paul when bitten by the snake, didn't give it much thought, and just shook it off in the fire. Paul also knew God had unfinished plans for him and no snake was going to stand in God's way. But I don't think Paul stuck his hand down there knowing he was going to be bitten. It happened, it was done, and Paul knew he was in God's hands.
God also requires us to take meaningful steps to preserve innocent human life. From building codes to involuntary manslaughter precautions to not allowing us to kill a fleeing thief.
God is sovereign in all things. Doesn’t mean we have no responsibility. His word says otherwise.
As far as applying that to the lockdowns, there is no precedent for denying people their civil liberties, lying, and fear mongering. No Christian need apologize for failing to participate in these evils.
