This sermon from Acts 3 shows the importance of worshipping together. Worship is a lifestyle. Worship is about sharing Jesus everywhere we go with everyone we come in contact with.
Peter and John worshipped by sharing Jesus and watching the Holy Spirit heal a paralytic. Then, in front of the same people who killed Jesus, they boldly proclaimed Christ. Finally, they REPORTED on the things God had done when they arrived with the other believers. Together, they prayed for boldness, to continue proclaiming Christ even in the face of persecution.
