Why is the concept of grace essential for Christian faith?

Grace is a cornerstone of Christian faith because it encapsulates the nature of God's relationship with humanity. 2 Timothy 1:9 states, 'Who has saved us and called us with a holy calling, not according to our works, but according to His own purpose and grace which was given to us in Christ Jesus before time began.' This passage elucidates that salvation stems from God's eternal purpose and is not contingent upon human merit. Grace conveys the incredible truth that God freely bestows His love and acceptance, regardless of our fallen state. It emphasizes the radical love and mercy of God that seeks to redeem humanity. Importantly, this grace not only saves but also sustains believers in their walk with God, enabling them to grow in faith and righteousness through the Holy Spirit's power. Understanding and embracing grace transforms a believer's life, encouraging a response of gratitude and worship, while fostering a sense of reliance on God's sufficiency in all aspects of life.
