Can you rephrase it with easier grammar and words? Also it sounds overly dramatic to say in the court, but is it normal?

Another way you can say this is: If I am lying, God can cut me open and tie my intestines around my neck. This sentence is very graphic and dramatic for a court session. Most people will not say this. He says this to try and convince the judge and the courtroom that he is not lying, and if he does, God will take out his intestines and tie them around his neck.
