What is the relationship between sin and God's grace according to this teaching?

The relationship between sin and God's grace is profoundly articulated in the sermon as the message of the gospel. The acknowledgment of our guilt, including the sin of murder, positions us to understand our need for divine grace. The sermon teaches that despite being guilty, God has provided a way for redemption through Christ, who was described as the Lamb slain from the foundation of the world. This emphasizes that salvation is not based on our merit but wholly on God's grace, which is sufficient to cover all sins, including the gravest ones like murder, providing hope for every believer.
