Paul, in writing to the church at Corinth of the gospel and hope of resurrection, writes...'If our hope in Christ is only for THIS life, then we are of all men the most to be pitied.' !st For. 15:19
The reason? Because, then - just as now, the church needed to be reminded that being in Christ meant victory not just over the penalty of our sin but the promise of life forever with God. One which included, as it did with Christ, a resurrection of our own body unto a new heavenly body to live with Him eternally.
