And I saw what looked like a sea of glass glowing with fire and, standing beside the sea, those who had been victorious over the beast and its image and over the number of its name. They held harps given them by God.Revelation 15:2 NIV
This is such a contrast with Revelation 13:7 where the beast is given power to make war on the saints and to conquer them. It this verse it is likely that we are seeing those saints who had taken the warning to faithfully endure (Rev. 13:10), and they are identified here as those who were victorious over the beast. While the beast (the Antichrist) may have put them to death, his victory was short lived. Because they endured to the end, they actually came out as the victors.
How do we judge success, or victory, in this life? Good job, big house, large bank account and investment portfolio, a stud or babe for a spouse, acclaim? Yet how many of those things will last? The only way to win in the end is to trust your life to Christ. And to be faithful, even unto death. Then you can join these who are victoriously standing before the throne. So what if you lose everything in this life? It is nothing compared to the glory that awaits us (Rom. 8:18). In all these things (tribulation, distress, persecution, famine, nakedness, danger, or sword) we are more than conquerors through him who loved us (Rom. 8:37).
