How do we know that grace is essential for living a Christian life?

In the sermon, it is stated that grace is not merely a concept but a person—Jesus Christ, who embodies God's grace toward humanity. The Apostle Paul strongly emphasizes that he does not view his life as precious to himself, as he is driven by the grace of God to fulfill his ministry (Acts 20:24). This understanding of grace leads believers to recognize their call to serve and love others selflessly. The transformative power of grace is what moves believers towards generosity and compassion, showcasing that a true understanding of grace will always result in an outward expression of that grace in our lives.
