What does the Bible say about the church's position in Christ?

The church's position in Christ is foundational to understanding sovereign grace theology. In 2 Thessalonians 1:1, Paul addresses the church as 'in God our Father and the Lord Jesus Christ'. This indicates that the identity and righteousness of believers are found in their relationship with Christ. They are not merely participants in a religious organization, but are intimately united with Christ in His death, resurrection, and exaltation. This union is critical because it is through this relationship that believers are seen as righteous before God, as their worthiness is not of themselves but attributed to Christ's perfect obedience and sacrifice.
