Ephesians 2 discusses the theme of salvation by grace through faith in Jesus Christ. The chapter begins by discussing the spiritual condition of believers before they came to faith in Christ- they were dead in their trespasses and sins, following the patterns of the world and the devil. However, through God's mercy and love, believers have been saved by grace through faith, and not by their own works, so that no one can boast. The chapter emphasizes that through Christ, believers have been reconciled to God and to one another, and are being built together as a spiritual temple. All believers, regardless of their past, have access to God the Father through Christ and the Holy Spirit.
