Why is understanding the nature of divine grace important for Christians?

Recognizing the nature of divine grace is vital for a Christian's faith and assurance. It fosters humility and gratitude, knowing that one's salvation is not based on personal merit but on the mercy of Christ. This concept is vividly portrayed through Matthew's calling; despite being a sinner without any virtue, he was chosen and called by Jesus. By grasping that God's grace is what makes us worthy, not our efforts, believers can more fully experience freedom in their faith, understanding that Christ’s work is complete and sufficient.
