What does "labor or cost of a godly life" mean?

[Richard Baxter](https://en.wikipedia.org/wiki/Richard_Baxter) , the famous Puritan writer, wrote: >In a word, that in all your neglects of duty, your **sticking at the supposed labor or cost of a godly life**, yea, in all your cold and lazy prayers and performances, conscience might tell you how unsuitable such endeavors are to the reward; and that Christ and salvation should not be so slighted.
