What Jesus is saying is that a right relationship with God will not be dependent on a something physical. It will not be necessary to go to a location or a special building to find a right relationship with God. Thus, cathedrals, temples, church buildings can never to declared holy. This building is only important in that it offers us an ability to meet together in a semblance of comfort. The church building is not a “holy place”. Nothing here is sacred apart from God’s people! Real religion will be based on the truth of God’s Word and on true affection for God.
