I have to admit that this world is difficult. There are sorrow and pain, we see mankind's pain on the internet.
The sadness increases in a person's life. It seems that this life promote sufferings.
Then a person can see joy in a person. People receive happiness when they buy a house. A person can be happy when that person receives money.
Houses and money will not give a person true happiness. Only Jesus can bring joy into a person's life.
Every human have a sinful nature. When a person desire to follow their sins then that brings sadness.
If a person wants to replace the sadness then that person needs to repent from their sins and follow Jesus.
Jesus is God. He died on the cross and conquered death.
