Not listening to God's voice can distance Christians from him and lead them instead to seek solace in worldly idols that offer only doubt and confusion, Pope Francis has said.

When Catholics are "deaf to the word of God", their hearts are hardened, and "they lose the meaning of faithfulness," the Pope said in his homily during morning Mass at Domus Sanctae Marthae.

The Pope began his homily by reflecting on the day's first reading from the prophet Jeremiah in which God laments the unfaithfulness of his people who "walked in the hardness of their evil hearts and turned their backs, not their faces, to me."
