Do we accept that we are NOT 'honoring' Him, as Jesus Christ mentioned? 

Mathew 15: 7. "You hypocrites! Isaiah was right when he prophesied about you: 

8. 'These people honor me with their lips, but their hearts are far from me. 

9. They worship me in vain; their teachings are but rules taught by men.'" (link to know the situation) 

We used to celebrate all the traditional festivals in a grand manner. 

We used to 'greet' each other. 

We will be busy with the 'preparations' like, shopping to buy new things, decorating the houses, arranging the parties, planning to spend the holidays, making some amusements, thinking 
in a different way to avoid 'boring-celebrations', etc., etc, 
only to honor Him. 

By the meantime, 
if time & mood permits, 
we used to praise the Lord 
and also used to worship Him. 

Then why the hell, 
He says us as hypocrites? 
Don't we honor Him? 
Are our hearts far from Him? 
Don't we worship Him? 
Are our practices & teachings 
created by us? 

Do we really honor Him? 
Are our hearts really with Him? 
Do we really worship Him? 
Are our practices & teachings 
as per His Teachings? 

Let's 'think' by ourselves...!

But, we are 'preparing' to celebrate the Christmas!

Do we 'respect & honor' Jesus Christ with all our hearts...?
Do we have any rights to 'celebrate' His Birth Remembrance Christmas...?

IF we atleast TRY to follow or remember or 'realize' our activities, then only it'll be meaningful to 'celebrate' the Christmas, The Birth Remembrance of Jesus Christ!
