The crowd rose up to take Jesus. His claim to know God, to be from God, to be sent by God was too much. They had Jesus’ death in mind as they reached out to grab Him. In John 7:30 we read: Therefore they sought to take Him; but no one laid a hand on Him, because His hour had not yet come. NKJV
They didn't believe that you could know God or that you could come down from God and to say either was blasphemy. They had their religion and their ways which involved the sacrifices and the rituals performed by the priests. For most, worship and devotion to God was for the priests to perform while they stood at a distance. Even for the priests, worship was a performance, a function but not a living reality.
The hour of Christ's death had not yet come so He simply walked away. In time, Jesus became the sacrifice offered and all that separates man from God was removed. Now we can have a relationship with God through His Son Jesus Christ. Our worship is spiritual because the physical need for sacrifice has been met in Christ's death on the cross.
Your eternal life begins when you accept Christ and are forgiven your sins. Then worship becomes personal and real, no longer bound up in form or function but now an expression of the joyous freedom you have in Christ.
