What is our work for God supposed to be, no matter what capacity he gives us?
In whatever capacity God gives, our work is to be for His glory and to further the work of the gospel. It is not for salvation but for reward. It can be as simple as dropping a word or having a short conversation that makes someone consider God's claims on their life.
Les explains that the one he describes had an expensive lifestyle, a family, and a beautiful home in Jerusalem, yet counted it all as dung for the sake of the gospel [s593-s597]. Les then connects this to being accepted of Him, whether present or absent—not for salvation but for reward [s599-s606]. He teaches that God leaves us here to further the work of the gospel [s609-s611]. In whatever capacity God gives us, our labor is to be for His glory and to further the gospel [s612-s614]. You never know when a word or a short conversation may cause someone to start thinking and considering God's claims on their life [s615-s621]. Les illustrates this with a man from the audience in one of his classes who liked to bounce these things off people by saying, 'think about it'; the next day a pastor returned, saying he was now searching the Scripture [s625-s643]. He adds, 'Eternity is long' [s650].
