Fishes living in bucket should not worry about what might happen

I got some Guppies. These are small colourful freshwater fish. However, they are not yet as domesticated enough as the goldfish. Which means they hide when you approach their bowl. I made a realistic marine aquarium for them with plants, rocks, and plenty of nooks and crannies to hide in.

I've been feeding them for quite a while now. But they don't seem to trust me. If I give them food, they will remain cautious and won't come up to eat unless I am gone or not moving for some time. While they are feeding, if I move the slightest, they will dart back down to their hiding holes. Today the same thing happened and I realized something. These fish live in a small aquarium, If I wanted to harm them, they could never defend themselves. No matter how much they hide or how scared they are of me, I can finish them in the blink of an eye. They should know that their fear is pointless and no amount of hiding can protect them. I thought the same about myself. We fear so much!! what might happen, what if I hurt myself, what if I fail, so many doubts pop up in our heads!! But we are like those little fishes in a bucket. If Allah (God) wanted to kill us, no amount of protection, hiding or fear could save us. So we should not live in fear or hide from challenges because if Allah wills we would be dead anyway despite we face our challenges or not.

We are all little guppies living in Allah's aquarium, we should be thankful that he is the most merciful and loving.
