What does the hope of His calling mean in Ephesians?

In Ephesians 1:18, Paul highlights the 'hope of His calling' as the assurance of eternal life and fellowship with Christ. This hope encompasses the promises of heaven, where believers will experience complete joy and fulfillment, free from sin and sorrow. It is rooted in God's redemptive purpose, as Peter describes it in 1 Peter 1:3-4, calling it a living hope through the resurrection of Jesus. This hope motivates Christians to live in light of their future inheritance, anchoring their faith through trials and uncertainties.
