How do you "worship in spirit and in truth"?

Can you be cast away and burned if you don't abide in Christ enough? What does it mean to worship God "in spirit and in truth"? How do you "stay right" with God? How can you be loving but also stand up for the truth of the Gospel? How does God's grace factor into my financial woes? If I keep struggling with a sin, does that mean I'm not repentant enough? Is there an end to the suffering in Hell? What about the flames themselves? Why don't more churches get politically active rather than going passive?
