If you are going to follow the Lord Jesus’ command exactly, and you say that it is not a dark saying, then you should show the great things the Lord Jesus has done for you only to those who are in your own household.
This would include your parents and siblings. If you have your own family, it would include your wife and children.
To follow the Lord’s command exactly, you should show it only to them, because they are the ones who are in “thine own house.”
LUKE 8:39
39 Return to thine own house, and shew how great things God hath done unto thee. And he went his way, and published throughout the whole city how great things Jesus had done unto him.
