What does it mean when St. Paul implores us to preach the Gospel? Does that mean we need to know every word of scripture and shout it from a soap box on a street corner? While this could be one way, I would argue St. Paul is talking about a more personal Gospel.
I once knew someone who was fond of saying that the Bible has many chapters, but it is only the first chapter in the larger Gospel, the Good News of God. She claimed each one of us, our individual stories, are a continuation of that Gospel. We all have episodes of time where we feel close to God, but then something, like sin, separates us from Him. He then restores the relationship with us, causing us to turn back to Him and His Church. Each of these personal stories that we hold in our hearts are little Gospels. When we tell others of these stories we are doing what St. Paul implores in 1 Corinthians 9: 16-19 .
When I first became Catholic, I hesitated to share what God did in my life, because I thought I might sound crazy to others. However, in every instance, when I thought it would be poorly received, I was met instead with open minds and curiosity, even while working in the secular world as a recruiter at ManpowerGroup Solutions.
As Simon says to Jesus in the Gospel of Mark 1:29-39, “Everyone is looking for you.” Everyone around us is looking for a savior, most spend years searching in the wrong places. It is our responsibility to share Jesus, by sharing the Gospel He works in our lives, with them, so they might see and hope in Him.
