The Ascension event allowed the disciples and the current worshiper to access the presence of Christ wherever they were located in time and space.
Even the resurrection appearances allowed Christ to be accessed only by those in certain locations. If Thomas was not with the rest of the disciples when the resurrected Christ appeared, the Thomas had no access to Jesus (John 20:24-29). Thomas had to be in the right location to confront the Christ with his challenge and to respond in faith. After the Ascension, access to Christ was open to any worshiper who drew near in heart and soul. In Christ there was full assurance of access to the Godhead wherever the worshiper might be located.
The expansion of the Church has been built on the principle that Christ and the Godhead can be accessed from any point on the globe and at any time in history. The worshiper is no nearer to Christ in the places of the historical setting of the Jesus of Nazareth. Pilgrimage can enliven faith by making real the geography of the Gospels and assuring the disciple that the gospel is not a fable. We know that the life of Jesus is rooted in geography and in history. Yet the access to the exalted Lord is readily available at whatever time and place suit the worshiper. Christians live by this assumption, but it is important to realize that the assumption rests on the doctrine of the Ascension.
