Is it really "finders keepers losers weepers"?
Here's the answer:
No, we do not get to keep everything we find. If we take something that doesn’t belong to us, that is stealing.
The Bible teaches us that it is wrong to take things that do not belong to us. We call it stealing, and Deuteronomy 5:19 says, "Do not steal." Sometimes people lose things that are important to them, like a pet or money. But just because a dog is lost or a 20 dollar bill is on the ground, that does not mean it is yours to take. The dog and the money both have owners. Instead of stealing them and claiming "finders keepers, losers weepers" it is best to find an adult to help you locate the owner.
Sometimes it is really tempting to take things that do not belong to us, especially if no one is looking. But God knows everything and He is always watching. The Bible says in Proverbs 15:3 "The eyes of the LORD are everywhere. They watch those who are evil and those who are good." God sees you when you sin and He sees you when you do good. It is best to always obey God and the Bible and do what is right even when no one else is looking. Returning something that is found to the owner is a good deed.
When you do something good, like returning a lost item, it brings glory to God. Matthew 5:16 says "In the same way, let your light shine so others can see it. Then they will see the good things you do. And they will bring glory to your Father who is in heaven." God wants us to be good like He is good. He does not want us to take lost items that don’t belong to us. Instead we should return the lost items to their owners.
"Do not steal. Do not tell lies. Do not cheat one another" (Leviticus 19:11).
"Suppose you see your neighbor’s ox or sheep wandering away. Then don’t act as if you didn’t see it. Instead, make sure you take it back to its owner...Do the same thing if you find their donkey, coat or anything they have lost. Don’t act as if you didn’t see it" (Deuteronomy 22:1, 3).
