What does being 'in Christ' mean for a believer?

'In Christ' is a profound expression encapsulating a believer's identity and union with Jesus. This union signifies that believers are not only identified with Christ's death and resurrection but also partake in His righteousness and life. As Ephesians 1:3 asserts, believers are blessed with every spiritual blessing in Christ. This means that all the promises of salvation, inclusion in God's family, and the empowerment for living a holy life are made available solely through this union. The new identity in Christ transforms how believers view themselves, others, and their relationship with God, calling them to live out their faith in light of who they are in Him.
