It is that kind of respectful, worshipful, adoring intimacy in friendship which we enjoy when we receive the life of Christ in the Holy Communion. We know in that relationship that he is no less our Lord for all his love and friendship, and now we obey him out of love rather than fear. It is love with intimate knowledge, knowledge of his true nature, knowing the nature of God. When we talk in this way of our relationship with Jesus it is about faith expressed in human terms of love and trust. These terms are readily understandable.
People can see that it is like the relationships of love that they know in ordinary human life.
The problem is that when power is added to it, love can be difficult. At least as adults, we are much more at home where there is love between equals. For children it may be different, but we are inclined to think that any exercise of power in a relationship of love must be exploitive. So if we love one whom we call Lord and master, in our culture we may have some problems. Many people would rather construct an image of God within themselves and relate to Jesus like an intimate friend than they would use those images of scripture in which Jesus is pictured as a King in glory, and God is envisaged as a great and glorious King.
