The fact is that Mount Sinai is a real place, and the Ten Commandments are equally real.
One day we will all have to account for our lives on this Earth, which is why Jesus Christ died for each one of us.
John 3:16-19 “For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
For God did not send His Son into the world to condemn the world, but that the world through Him might be saved.
He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.” NKJV
