How are the things God did for us at salvation appropriated?
The things God did on our behalf at salvation are appropriated only by faith. The moment a person believes, all the good things God does on their behalf are received, not by works or human effort, but solely through faith. Salvation and all it implies must be appropriated by faith.
Les explains that in Romans chapter 1 he laid out all the things God did on our behalf the moment we believed. He took off on the word salvation and all that it implies, and he emphasizes that all of these things have to be appropriated only by faith. They are the good things God does on our behalf when we believe.
