What is your identity?
Are you "just an old sinner saved by grace."or a saint (holy, righteous child of God)?
Apostle Paul, as he writes to different assemblies, he addresses them by calling them saints:
To all in Rome who are loved by God and called to be saints - Romans 1:7
To the church of God in Corinth, together with all the saints throughout Achaia - 2 Corinthians 1:1
Paul, an apostle of Christ Jesus by the will of God, To the saints in Ephesus - Ephesians 1:1
Paul and Timothy, servants of Christ Jesus, To all the saints in Christ Jesus at Philippi - Philippians 1:1
giving thanks to the Father, who has qualified you to share in the inheritance of the saints in the kingdom of light. - Colossians 1:12
It looks like the believers in Rome, Corinth, Ephesus, Philippi and Colossia were called saints, although their actions weren't so much saint-like all the time. Those were ordinary people just like you and me, they pretty much looked like you and me (may be even bad), they didn't act holy all the time, they had problems in their lives just like you and me, they had questions and confusions, they didn't have the Bible like you an I have it today, they didn't have a stack of 'how to' christian books in their living room, they weren't perfect parents, husbands, wives or children, yet Apostle Paul called them "saints". In other words, God call them "saints". And God call us saints, because we have the very same righteousness of Christ Jesus. Is it too good to be true?
