How does grace play a role in a Christian's security?

The concept of grace is pivotal in the Reformed tradition, particularly as it relates to a believer's security in Christ. Our justification and acceptance before God are products of His grace alone, as articulated in Ephesians 2:8-9, which affirms that salvation is not of works but a gift from God. Consequently, a Christian’s security rests not on fluctuating feelings or personal righteousness but on the finished work of Christ and the promises of God. As David reflects on God's blessings in his life, he points to the sufficiency of divine grace that preserves the believer. This assurance of grace provides believers a steadfast foundation, offering peace and comfort in their journey of faith.
