It is possible that, even in prayer itself, we could refuse to let ourselves be confronted by the freedom of the Spirit, who acts as he wills. We must remember that prayerful discernment must be born of a readiness to listen: to the Lord and to others, and to reality itself, which always challenges us in new ways. Only if we are prepared to listen, do we have the freedom to set aside our own partial or insufficient ideas, our usual habits and ways of seeing things. In this way, we become truly open to accepting a call that can shatter our security, but lead us to a better life. It is not enough that everything be calm and peaceful. God may be offering us something more, but in our comfortable inadvertence, we do not recognize it.
Naturally, this attitude of listening entails obedience to the Gospel as the ultimate standard, but also to the Magisterium that guards it, as we seek to find in the treasury of the Church whatever is most fruitful for the “today” of salvation. It is not a matter of applying rules or repeating what was done in the past, since the same solutions are not valid in all circumstances and what was useful in one context may not prove so in another. The discernment of spirits liberates us from rigidity, which has no place before the perennial “today” of the risen Lord. The Spirit alone can penetrate what is obscure and hidden in every situation, and grasp its every nuance, so that the newness of the Gospel can emerge in another light.
