Are Christians Who Continue to Sin Hypocrites?

Questions about sins of action vs. sinful character flaws and whether continued sin makes Christians hypocrites, whether Ananias and Sapphira were saved, and whether Christians aren’t practicing what they believe if they’re spending time and money doing anything but evangelize.

• What’s the difference between sins of action and sinful character flaws, and does continued sin of either form make Christians hypocrites?
• Do you think Ananias and Sapphira were saved if they had accepted Christ as Lord and Savior, despite their massive blunder/punishment?
• Given the stakes of temporary time to choose an eternal destination, why do any Christians do anything but evangelize? Why do churches have state-of-the-art equipment and buildings for a temporary time when they preach an eternal reality? It seems like they’re not practicing what they believe.
