Why aren more miracles done to convert people to Christianity?
“When only a miracle leads a person to acknowledgment of God and to adoration and piety, he acts from the natural and not the spiritual man. For a miracle infuses belief by an external and not an internal way, thus from the world and not from heaven. The Lord enters man by an internal way, by the Word and by doctrine and preaching from it. As miracles close this way, no miracles are done today” (Divine Providence n. 131).
