Oh Jesus say something, talk to us

I will tell you all a story.

There was a man. he had two sons.
once he asked one of his son to go to the yard and clean it.

He denied at first, then after some time. he wents to the yard and started cleaning it.

Then he asked his second son to go
to the yard , to do the same.

he agreed momently ,
but later
he didn't go .

Now you all tell me which son is worthy...
