Christ's

When John, who was in prison, heard about Christ's deeds, he sent two of his disciples to ask him "Are you the one who is to come, or should we expect another?"

For Christ's sake, stop it!

Peter denied that he was Christ's disciple.

Peter not only denied that he was Christ's disciple, but that he even knew him.

For Christ's sake, leave the man alone.

For christ's sake, this is useless!

The book of Acts describes how Christ's message was spread and the first churches were formed.
