How do we know grace is essential in the Christian life?

Grace is foundational to the Christian faith, as it is through grace that we are saved and brought into a relationship with God. Ephesians 2:8-9 teaches that we are saved by grace through faith, not of our own doing but a gift from God. This grace reflects the character of God and serves as the basis for all Christian living. In the context of Philemon's letter, Paul pleads for grace in the relationship between Philemon and Onesimus, underscoring the need for forgiveness grounded in the grace that Paul himself received from Christ. Every believer is called to reflect this grace in their interactions with others.
