If I were to ask you what you were doing last year, you may try to remember. At least that would be a valid question, because you were doing something a year ago. But if I asked you what you were doing a thousand years ago, you couldn’t answer that. You weren’t doing anything because you didn’t exist!
Jesus was in existence long before the world came to be. We find His own supporting testimony of this when He said, “I tell you the truth,” Jesus answered, “before Abraham was born, I am.” (John 8:58)
