This law is that just as we like other people to do for us; we must also do for others.

It says in Matthew 7: 7 “Ask, and it will be given to you; seek, and you will find; knock and it will be opened to you. ”
There is also a proverb from the elders that says:
“How good it is to eat hungry; drink water thirsty; talk to who understands me and ask whoever gives me.
These two sayings have something in common, in both it refers to satisfying our needs, but it also teaches us that we must put into practice the love of our neighbor, that is to say that if someone asks us, let's give; if they look for us, do not get lost, and if they knock on our door, do not hesitate to open; well we don't know the need of that person.
The word teaches us that even if we are bad, we can do good to those who need us. How much more will God do if they ask Him.
