SAINTS: A BIBLICAL PERSPECTIVE
I) ALL BELIEVERS ARE SAINTS, SET APART TO GOD
A) [2 Thes 1:10]:
"When He comes to be glorified in His saints on that day, and to be marveled at among all who have believed - for our testimony to you was believed.'
"Saints" = "hagios" = separated, set apart to God, as those who have been born again into the family of God as His children, declared righteous and sealed unto eternal life in Christ by God the Holy Spirit. Notice that saints are identified as 'all who have believed.'
B) [Eph 1:1]:
"Paul, an apostle of Christ Jesus by the will of God,
To the saints in Ephesus, the faithful in Christ Jesus"
C) [Rom 1:7]:
"To all in Rome who are loved by God and called to be saints"
D) [1 Cor 1:2]:
"To the church of God which is at Corinth, to those who have been sanctified in Christ Jesus, saints by calling, with all who in every place call upon the name of our Lord Jesus Christ, their Lord and ours."
The church of God at Corinth, i.e., believers are identified as 'saints by calling'.
E) [2 Cor 1:1]:
"To the church of God in Corinth [all believers], together with all the saints throughout Achaia"
"To the church of God.... together with all the saints throughout Achaia" = Notice that those who are members of the local church in Corinth, i.e., believers, are equated with all the saints from the province of Achaia within which is located the city of Corinth. So all believers are saints.
