We who have undertaken Christ's Missionary work should also imitate his constancy in prayer and take to heart his recommendations and teachings on prayer without ceasing.
For this reason, we should cultivate the spirit of adoptive sonship whereby we cry: "Abba, Father!" Led by the light of faith, we should search for signs of his will in what happens in our lives, thus growing daily more responsive to our mission.
Before we dutifully proclaim the Lord's word, we should first listen to it in attentive meditation and also share it with our brothers so that we ourselves may be converted to the Gospel, become conformed to Christ and set afire with his love, the force that should impel us. Finally, in our prayers and petitions, we should intercede with God for the Church and for the life of the world.   (Constitutions... nn. 33 y 34)
