What they say in the video is this: "To worship God and to benefit from his (no capital in jw.org subtitles) guidance, is the real purpose of life. And he (again no capital) doesn't want our life to end. (emphasis on your life to end in Armageddon, but they don't tell you that in the beginning)
If we accept that truth we can have a life with real purpose, both now and forever.
So what is the truth according to Jehovah's Witnesses?
In their own words:
The faithful and discreet slave is the governing body, the leadership of Jehovah's Witnesses!
jw.org does not use a capital letter for God in 'his' and "he" in their own subtitles btw, Elaine Bailes from jw escape Youtube channel, noticed that in a Watchtower study article they do use a capital when referring to the devil.
