Good question.
I love being part of something that goes back over the ages and all over the world.
I love the feeling of community and belonging, all ages together in one purpose. Not always perfect, of course, but beautiful when we get it right.
I love the sense of completeness and wholeness. I feel God gives me such a sense of worth and value. I love the hope and purpose I experience in my faith.
I love that even on darkest days, in the midst of crappiest times I know God is here, walking with me, holding my hand, knowing the pain and weeping with me.
I love worship, especially through singing together with thousands of others, joined in something so utterly incredible and uplifting. I love it on my own too or in a service with a few. Worship to me is not a duty to appease a god but a pleasure and privilege to unite with God in intimacy and belonging.
I love the church year and festivals, the feeling of joining with others through history. The tradition of it.
And yes the reference point of something absolute when it comes to morality. Doesn't make me better than unbelievers but gives me a peace and safety in how I live my life.
I love the peace beyond understanding, for it really is that.
I love Easter! :-)
