The document discusses the importance of evangelization for lay Vincentian volunteers. It emphasizes that volunteers must share God's love with those living in poverty who may not know how to love due to lack of being loved. Volunteers are challenged to evangelize the poor so they come to know God's love for them. Both charity and preaching the Gospel are necessary, as one cannot exist without the other. Volunteers must offer both material and spiritual aid to those in need. Their charitable actions and commitment to justice and evangelization make the Church credible.
