The blood of Jesus which was shed for sinners was before the resurrection took place, Jesus was and is and will be superior all the time, His virgin birth, His ministry, and His death, also in His resurrection. Unless He Himself gave His life for sinners, no one could kill Him. (John 19:11 ) Jesus Christ is the same yesterday, today, and forever. (Hebrews13:8) He is mightier all the time. He can do everything but He didn't want to show up. This doesn't mean that He couldn't do anything before His resurrection.
