Tres Dias is a Christian movement that focuses on spiritual renewal and community building. It typically involves a three-day retreat where participants engage in talks, discussions, and activities designed to deepen their faith and strengthen their relationship with God. The program emphasizes the importance of living out one's faith in everyday life. During the retreat, participants are encouraged to reflect on their personal beliefs and experiences. The event is often led by a team of volunteers who have previously attended a Tres Dias weekend, fostering a supportive environment for newcomers. The ultimate goal is to inspire individuals to become more active in their faith communities.
