Here, as Alma is feeling like a failure, an angel of the Lord comes and tells him to rejoice! The Lord wasn't concerned that Alma's time in Ammonihah hadn't yielded immediate or measurable success, he was rejoicing in the fact that Alma had been obedient to what the Lord asked of him. Can you and I get ourselves to believe that the Lord is pleased with our efforts? Even on days when we feel like we've failed?
