God does expect us to give all unto him. However, this does mean different status depending upon your state in life. If you are married, that doesn't mean enter a chapel 24/7. That would not please God. Instead, you please God by doing everything to be a virtuous husband/wife and by raising your children in a holy manner, and by doing your best to observe God's commandments.
And, finally, I agree with you that protestant mega-churches are a perversion of Jesus's message due to both doctrinal errors and attachment to money, and I fear that they will one day be like parable of the 10 virgins in the Bible:
"Later, the other virgins arrived and said, ‘Lord, Lord, open the door for us!’ But he replied, ‘Truly I tell you, I do not know you.’"
