For me Christmas is day when you're celebrating Holy Spirit, Christ, born and saving us from unending bound of sin by sacrificing Himself on the cross. It's remind me how hard that struggle to break out from the darkness that covering this world since the Fall of Adam and Eve to sin.
And one more thing, did you think Jesus Christ was happy when you're celebrating His Birthday? Absolutely yes. You're remember Him, idolize Him, last wanted to be like Him, Holy and winner from death realm that raised to Heaven.
But beside of that what is the good point you got from Christmas? Changes in Your Life to His Holy reside.
