Today, a friend of mine asked me, what does "That which" mean. They gave me one examplea said they saw it on a game:
"Shinning as lucifer, the morning star, in the dawn, showing a beauty that is not God's — *That which* appears withing graps"
Also, they gave me other example:
"That which doesn't kill us, it just makes us stronger"
And I couldn't answer. Could you guys help me? Thanks in advance.
