Inclusion and separation

My church is a fundamentalist church, and emphasize on Biblical Separation based on 2 Corinthians 6:17. But there is also Biblical Inclusion (Acts 10) where we should bring the Gospel to all. However, we have to obey God's timing and direction. The Holy Spirit directed Paul to turn from Asia to Macedonia (Acts 16:6-9). Thus the Gospel went to the Roman Empire and later to Europe.
