John 7:34 You will seek Me and not find Me, and where I am you cannot come.
When Jesus was speaking to the Pharisees He told them they would continue to seek Him (the Messiah) and they would not be able to find Him. This intimates they would continue looking for a Messiah having missed the point that He is our Messiah and He has already come.
Many times in our lives we do not believe what we see because we either expect more or we want more, or in this case they wanted something different!
Jesus Christ has already come to save us from our sins and He has already shed the blood He promised and has already paid the debt in full.
Believe and trust in Him.
