God was preparing Lucia before the visions took place. Father Joe notes that Lucia's mother urged her to ask God to make her a saint, and Lucia made a self-offering.

Our Lady looked sad after the Miracle of the Sun, telling the children that God was offended by the sins of the world. Father Joe calls us to holiness to fulfill Our Lady's plan for our salvation. 

The readings for this homily: https://bible.usccb.org/bible/readings/011226.cfm Father Daniel Klimek, PhD reflects on the beginning of Christ’s public ministry and the radical call of discipleship. When Jesus calls the first apostles, He does not simply invite admiration, but demands surrender. Peter leaves his nets behind—his livelihood, his security, his safety—to follow Christ. Those nets, Fr. Daniel explains, symbolize the attachments and “safety nets” that often keep us from deeper freedom in God.
