I'd like to say a word about incarnation, being a Christian and all. This (besides resurrection), is one of the neatest bits about Christianity to me. God became a human, was born out of a woman, was a baby, grew up, died - just like I will.
The God who knows me is no stranger. Ze incarnated into this world, and by becoming human, enabled me to become a God's daughter.
This is, now, of particular importance because I'm going through my past, hopefully finally expunging some demons of old. It's painful, and difficult to do it, but somehow it comforts me to know I'm not doing it alone. My suffering is God's suffering - Ze shares in it, and likely my suffering is part of Jesus' suffering on the cross. We're taking the sins of humans (and make no mistake, forcibly sexing and gendering other people is a sin) on our flesh and suffering because of them. It doesn't make us any better people - suffering doesn't make you better, it just hurts, maims and kills.
I know the preceding might not sound very happy to many people, but please give it some thought: I'm at my happiest when I'm present in this world, and suffering and pain are present here, now. There's a forceful happiness in knowing what you are and what's happening to you, even if it's painful and makes you suffer. See, the other option, for me, is not not suffering, but numbness. Not feeling anything, not being connected to anyone - not living, in fact. I prefer life very much to living death.
That God can, and does share in my life is a very happy occasion, and Christmas is the yearly happy reminder of that. Happy Christmas!
