Zechariah 7

Then the word of the Lord of hosts came to me, saying, “Say to all the people of the land, and to the priests: ‘When you fasted and mourned in the fifth and seventh months during those seventy years, did you really fast for Me—for Me?  When you eat and when you drink, do you not eat and drink for yourselves?  vv.4-6

Outward religion without inward reality leads to spiritual sclerosis. 

(Steven J. Cole, 2003, www.bible.org)

Now that the Jews are no longer in captivity they have questions about what ordinances they should still uphold.  The come to ask Zechariah if they should continue fasting now that their back from exile.  Yet the Lord's response through Zechariah really seems to call them out of these petty questions they're asking as if they're doing it to be patriotic or religious and not really having learned from their fathers disobedience which led to their captivity.  Zechariah didn't want this next generation to fall into the same ways as their fathers, but some signs of that were beginning to show.  Zechariah recaps what the prophets were saying to Israel that they choose to harden their heart towards and this was to 
"Execute true justice,
Show mercy and compassion
Everyone to his brother.
10 Do not oppress the widow or the fatherless,
The alien or the poor.
Let none of you plan evil in his heart
Against his brother." (vv.9-10)
 What petty or meaningless things do you focus on in the name of spirituality rather than on a heart for God?  Ask yourself why you do what you do when it comes to activity for God?
