I think for some, not all, of the DeChurched, THIS is how they feel. They don't quite fit in to what the church is telling us we have to do. How they must look. They just can't seem to physically adjust the way God's made them to perform the way the church has told them they must. So. They quit.
I'd just want to add that God did not set this mandate for how many churches try to train it's members to perform. Yes, God did give us guidelines to follow for our safety, protection, and inevitably to show us how much we need Him and the salvation he offers. But the fence before the fence before the sin was put up by the Pharisees. The ones that think they actually can make it on their own. They've created man-made traditions to adhere to in hopes to seem more righteous before men but are lost and separated from their savior thinking they don't need saving.
Lets rethink first position that's is hard to maneuver and the plié that makes the newbie fall on their tush while the experts giggle amongst themselves. Let's instead stretch out the hand of love and teach each other to walk the straight and narrow path with as little fancy pants dancing down the path as possible.
If I speak with human eloquence and angelic ecstasy but don't love, I'm nothing but the creaking of a rusty gate. If I speak God's Word with power, revealing all his mysteries and making everything plain as day, and if I have faith that says to a mountain, "Jump," and it jumps, but I don't love, I'm nothing. If I give everything I own to the poor and even go to the stake to be burned as a martyr, but I don't love, I've gotten nowhere. So, no matter what I say, what I believe, and what I do, I'm bankrupt without love. (1 Corinthians 13:1-7, The Message)
