Why are we to work in the Lord's vineyard in this life?
Believers work in the Lord’s vineyard in this life because they are to expect rewards someday, when they come before the bema seat for rewards. This is tied to the first resurrection, where believers of all ages will rule and reign with Him for a thousand years.
Les explains that future events include the marriage of the Lamb and coming before the bema seat for rewards. The reason believers are to work in the Lord’s vineyard in this life is that they are to be expecting rewards someday. He connects this to the first resurrection, in which believers of all ages will rule and reign with Him for a thousand years. Les also notes that I Corinthians 15 is the great resurrection chapter, where Paul deals with resurrection in plain, simple language and uses common, ordinary, everyday events to describe it, writing that Christ is risen from the dead and has become the first fruits—plural—of those who have died.
