The Father: I've always thought of the Father as a way of thinking about our relationship with God, without ever thinking about what that might mean specifically, just only as a feeling. Thinking of it now, I don't think that I have ever actually thought of God that way, but maybe now I will read those passages again where Jesus talks about God as our Father.
The Son: For me that only means that He's the ruler of God's kingdom. It has nothing to do with the way He was born.
The Holy Spirit: The importance of the Holy Spirit for me is to see more possibilities in what we do than just the effects of our own actions, that that there's a power and influence that will sometimes amplify and multiply the effects of our efforts to serve the kingdom.
