God “does not ration his gift of the Spirit” (Jn 3). God enters into us and into our lives so far as we are open to the divine presence and action. We are free. God will never revoke or violate the freedom by which we resemble God. Though love is a commandment, God works through our freedom; God is an inviter.
It is not easy to be open to God. Desires get in the way. It isn't popular any more to talk about detachment. Nevertheless, the laws of the spiritual life have not been revoked. All great spiritual masters, including those who were not Christian, have required detachment, as the royal road to enlightenment; Christians seek perfect love. Jesus, the Word of God, said very clearly, “Where your treasure is, there your heart is also” (Mt 6). The gift of the Spirit enters into us whenever we voluntarily abandon any desires that get in God's way. In practice, that is a weaning process that takes a lifetime.
Lord Jesus, I freely renounce any desires which interfere with your saving, healing work within me. When I weaken, strengthen me with a reminder of your love.
