How do we know that Jesus reconciles us to God?

Ephesians 2:16 gives a clear affirmation that through Jesus' death, both Jews and Gentiles are reconciled to God in one body. This unity reflects the profound truth that Jesus' sacrifice abolishes the enmity created by the law of commandments. His atoning work is essential because all have sinned and fall short of the glory of God, and it was at the cross that Jesus not only bore our sins but also established the means of reconciliation for all who believe in Him, regardless of their background.
