Grace is fundamental because it emphasizes salvation as a gift from God, not based on our works.
Grace is the foundation of our salvation and understanding it is crucial for Christians. Ephesians 2:8-9 teaches that we are saved by grace through faith, and this not of ourselves; it is the gift of God, not of works, lest any man should boast. This reveals that our salvation is entirely dependent on what God has done rather than any merit of our own. It establishes a relationship of dependence on God's mercy and love, not our works. Furthermore, understanding grace helps Christians to live joyfully in the assurance that their sins are forgiven and that their relationship with God is secure—not based on performance, but on Christ's finished work.
