There are a few that God calls them His friends, but what about the others? There is likely more that He calls His servants and then what about them and the others? If He is not calling you His friend then I imagine He won’t speak to you like He is your friend, If He is not your friend or you are not His friend how would you speak together like friends. It is also the same in human relationships, one can only speak as a friend to one when they really are friends. When one is a friend of God, they can introduce God to another to be friends with Him also, if one is just a servant then they can only introduce God to one as a servant. When one is friends with God how can they be friends with those that are not whether they be servants or whether they be pagans. But a friend of God can give invitations, but it is up to those that receive the invitation to either come or not.
