Enthusiasm
Jesus declares - he does not determine any quota of his gift of the Spirit. To love Jesus and to be faithful to him is to open to his superabundant gifting. Jesus himself received a lot from the Father: the power to judge (Jn 5:22, 27), the power to give life (Jn 5:26), the divine name (Jn 17:11), and glory (Jn 17:22). These, he now offers to all who come to him.
The glory of the Resurrection is then an invitation for us to shine also with all the love and goodness that God has poured into our humble being. This is what being “enthusiastic” means. Enthusiasm comes from the Greek expression en (in) + theos (God). The true enthusiasm bursts forth with all the goodness and glory of God.
