In his book, “A well-build faith: a Catholic’s guide to knowing and sharing what we believe”, Joe Paprocki writes:
“To believe is to enter into a relationship with another and to place our trust in that person. Until that happens, what we have is not a belief, but an idea. An idea evolves into a belief when it makes the leap from the head to the heart. Belief or faith is not blind. It is grounded in reason. We do not intimately love another person unless we have good reason (and some degree of evidence) to think that this person can be trusted. In the same way, we place our faith in God, not blindly, but based on good reason and some degree of evidence that God can be trusted. What is that evidence? Namely, the story of salvation history and the living witness of other followers of Christ. The Sacred Scriptures tell us the story of how God has been faithful to his people since the dawn of creation. The living witness of the saints – those canonized and those quietly leading lives of faith – provides us with credible evidence of the trustworthiness of God. Our own experience can also lead us to believe that God can be trusted. And yet, in the end, we have no proof, no guarantee – only an invitation to trust. And so, when we say in the Creed, ‘We believe in one God,’ we do so at our own risk. “
To help people to believe in Christ, we are to help them to trust God. The three main works for us are: 1) helping people to understand the meaning of the Scripture; 2) living out a faithful life; and 3) inviting people to experience God in their own life.
