Jesus, the dearly loved Son, was always turned towards his Father in love. He delighted in his Father. He obeyed his Father freely from love. He always honoured the Father because he loved his Father more than his own life. In all these ways, Jesus related to his Father in the Spirit so that he overflowed with joy in the Father. As we look at Jesus we also see the Father turned towards his Son in delight. Jesus is the beloved Son in whom the Father is always well pleased. And the Father was continually present to Jesus with delight in the Spirit.
So when we look at Jesus the first thing we see is that God is a fellowship of self-giving love. In this fellowship, the three are continually sharing in each other’s delights and desires, in each other’s loves and longings, in each other’s pleasures and pursuits. They are dynamically one in the sharing of life and love. C.S Lewis called this “The Great Dance”.
Apart from Jesus, we know nothing of the Triune God in the eternal realms. But what we see in Jesus during his earthly life unveils who God is eternally. God is a fellowship of mutual joy and love and life and energy and joy. He is not a still and static essence; he is a joyful fellowship sharing a fullness of life and love. In himself, apart from us, God IS love and he is love in dynamic and personal fellowship. It is this God, who now calls us to walk in love as we live in him and he lives in us.
