The reason why I cringe when I wake up on a Sunday morning. And I had no choice but to go back when I was a kid. I really don't see what exactly is so "spiritually enlightening" about going to Church anyway, because it's just the same exact 2-3 hour service every week, even if they sing two different songs about God's love and Jesus Christ. And I always get that nagging feeling that it's just not natural or right to force oneself to endure hours of monotonous singing and the same old tired speech about how we're all sinners and Jesus loves us.
And yeah the Church claims to promote peace and love, even though it killed millions in the past in the name of God. And I don't see what's the whole point of praying to God for help when he hides himself and refuses to answer our prayers.
