The perfect Holy Trinity consists of three separate persons who all share the same essence; the Father, the Son, and the Holy Spirit. However, how does this abstract ancient mystery apply to our everyday lives?
We are made in the image of God. “God created human beings in his own image. In the image of God he created them; male and female he created them” (Genesis 1:27). In many ways we are an imperfect reflection of the Holy Trinity. The Trinity lives and breathes within us, around us, and through us. Psychologically within each one of us we have three distinct ego states; that of the child, the adult, and the parent who all share the same nature and essence because they are all contained within one single person. In such a way, the love of God is hopefully alive and flowing amongst the imperfect reflection of the trinity in each of us.

God is also reflected in loving human relationships. “For where two or three are gathered together in My name; I am there in their midst” (Matthew 18:20). In human interactions we tend to triangulate. We have sin and suffering within all our human relationships. It is only by the grace of God that we can continue to love and forgive each other as we reside and function within the imperfect trinity of victim, persecutor, and rescuer.

In the holiest of relationships we can enjoy a small taste of heaven on earth. These relationships require that each person is seeking to bring the pure goodness of God to earth. The motivations of each person’s human heart must be unselfish, pure, aligned with Biblical teachings, and respectful of each other. “This is how all will know that you are my disciples, if you have love for one another” (John 13:35).
The unselfish love flowing amongst the persons of the Holy Trinity never loses this perfect nature whereas we humans can only hope, by the grace of God, to taste briefly of such Divine Love here on earth. God lives in me. God lives in you. Therefore, God lives in us. United together in his merciful love we are so much greater than each of us could ever hope to be all alone.
