The Chinese word for “me” is 我. The Chinese for “lamb” is 羊.
The Chinese for “righteous” is 義, it’s a combination of those two. The lamb on the top, and me on the bottom. Possibly from the ancient days when anyone who had done anything wrong might sacrifice a lamb to their god to cover over their sin.

In the Old Testament (the Jewish scriptures) they were told to sacrifice a lamb if they broke the rules. But they were told the blood of that lamb would cover over their offence. (Not take it away, just cover it over).

One of the names of Yeshua is “The Lamb of God”. And his death didn’t just cover it over, it took away our offence permanently. So when you become a Christian it’s like you’re accepting the sacrifice of the Lamb of God on behalf of you. His sacrifice makes you righteous in God’s eyes. If you think about the lamb being over you, like the Chinese character, it’s kind of like God looks down at you but only sees the lamb above you instead of seeing you, and thinks to himself, “righteous”.

Yohannes the Baptiser saw Yeshua walking along one day, and told his followers, “Look, the Lamb of God, who takes away the sin of the world.” He has taken away your sin. You only have to accept that and put yourself under the lamb to have every wrong thing you ever did forgiven.
Put yourself under the lamb, so that when God looks down on you he sees the lamb, and declares you righteous.
