Been There, Done That from Randy Alcorn - EPM on Vimeo.
In response to the question, "Will we be able to fall into sin again?" Randy Alcorn emphasizes that in the life to come we will have Christ's righteousness as well as the memory of what life in sin was like. So we will have no desire to ever go back to sin again, and thereby will not be capable of another fall. This video clip was excerpted from Randy's Eternity 101 DVD class.
