Worship is more than what we do in our corporate gatherings. Jesus is the fulfillment of the entire system of worship under the Old covenant; particularly the priesthood, sacrificial system, and Temple. Being united to Christ by Faith, the Christian himself/herself is now the location of where worship takes place.
The Bible clearly shows that not all of our attempts at worship are true or acceptable. We must strive to offer true worship - worshiping the true God, the right way, with the right attitude. Also, we must not limit this true worship to Sunday morning gatherings. The Scriptures call us to a lifestyle of worship, affecting our decisions and desires on a daily basis.
God's patience is demonstrated as he sends and sends his invitation to the Gospel. However, we see that gracious invitation rejected three different ways: casual indifference, bold defiance, and false profession. The only ones allowed to enjoy "the wedding feast" are those who, through faith, receive God's gift of righteousness.
