The video and many denominations including the RCC just make it more complicated than it needs to be. We can spend our whole life working to help others and miss the gospel message. There are nothing wrong with good deeds, however, it can work to hide the simplicity of the gospel. Our reward, however, is tied to what we do because Revelation tell us when Jesus returns He "will give to everyone according to what they have done". But, if what they have done, failed to believe the gospel their reward will be diminished until they believe the truth.
