What does this means

John's words sound strange in a world afraid to tell the truth about sin, wickedness, and evil. Yet all lost people — people who do not know Jesus and those who claim to follow him but don't obey him — we all desperately need to repent. That means changing our hearts and lives, seeking after God, and turning our behaviors around to live for Jesus as Lord. We choose to follow and obey him, not our wants. Yes, salvation is given to us by God's incredible grace. On the other hand, grace that leaves us unchanged is not true grace. Grace not only forgives us through Jesus' sacrificial death on the Cross and our faith in him but also liberates us from the empty and destructive life without God, his guidance, and our purpose.

This passage is emphasizing the importance of repentance, seeking after God, and living a life for Jesus as Lord. It highlights the need for individuals, both non-believers and those who claim to follow Jesus but do not obey him, to change their hearts and behaviors in order to truly follow and obey Jesus. It also stresses that while salvation is given by God's grace, true grace also involves a transformation in one's life and liberation from a purposeless and destructive existence without God.
