The pope suggested that a good way to counter distraction and to distinguish the voice of Jesus from competing voices was to read the Word of God daily.
"And I return once more to that advice: always keep with you a handy copy of the Gospel, a pocket edition of the Gospel, in your pocket, in your purse ... and so, every day, read a short passage, so that you become used to reading the Word of God, understanding well the seed that God offers you, and thinking about the earth that receives it," he said.
He also encouraged Catholics to seek help from the Virgin Mary, the "perfect model of good and fertile soil."
After reciting the Angelus, the pope recalled that July 12 was Sea Sunday, an annual observance marked throughout the world, saying: "I extend warm greetings to all those who work on the sea, especially to those who are far from their loved ones and their country."
In improvised remarks, he added: "And the sea carries me a little farther away in my thoughts: to Istanbul. I think of Hagia Sophia, and I am very saddened,"
The pope appeared to be referring to Turkish president Recep Tayyip Erdoğan's decision to sign a decree July 10 turning the ancient former Byzantine cathedral back into an Islamic place of worship.
Addressing pilgrims gathered in the square below, who stood apart in order to prevent the transmission of the coronavirus, he said: "I greet with gratitude the representatives of the Pastoral Ministry for Health from the Diocese of Rome, thinking of the many priests, women and men religious and lay people who have been, and remain, at the sides of the sick, in this time of pandemic."
