If we determine to honor God with our lives, regardless of the obstacles and setbacks we face, then… the testimony of our lives will be more than enough: "…They shall eat, and shall leave thereof".
…the Believer who is completing his course of suffering for Christ's sake is completing the process of ceasing from sin. In other words, suffering for Christ's sake transforms the Believer from sin-FULL to sin-LESS; suffering for Christ's sake perfects Believers.
