The Sacred Heart of Jesus is a Christian symbol representing the love and compassion of Jesus Christ for humanity. It is often depicted as a heart surrounded by thorns, symbolizing the suffering He endured, and sometimes includes flames, representing divine love. This devotion emphasizes the importance of Jesus' heart as a source of grace and mercy. The devotion to the Sacred Heart is particularly prominent in the Roman Catholic Church, where it is celebrated on the feast day of the Sacred Heart, typically observed 19 days after Pentecost. The image and devotion encourage believers to reflect on their relationship with God and the unconditional love offered through Jesus.
