"And I see how this looser approach to worship is reactionary to what's perceived as 'dry religion' of more traditional liturgies. But I'm appreciating the richness, thoughtfulness, and depth woven into liturgical worship. I think evangelicalism can gain a lot from it."

I think the Christian religion can gain a lot from the gospel instead of displays of religious fervor.

The Pharisees were picture-perfect at outward professions and shows of 'visible worship'. They had a beautiful temple and a very orderly liturgy. Christ called his disciples to something greater.

"The kingdom comes not with observation."

"Repent" means "turn the mind". Turn the mind from what, to what?

Modern Christians generally say to turn from sin and become religious.

But that is NOT how the bible defines repentance.

Sin is the symptom of the thing men need to repent of. The core cause of sin is idolatry--idols--false gods, false christs, false gospels, false teachings, and false priorities. That's why repentance is a thing of the mind. We have too much religion teaching people to struggle with their sinful flesh or improve their religious optics and not enough raw faith teaching the good news that one man on Golgatha already defeated that monster. We cannot add to Christ's work on the cross and yield right results.

Once repentance comes, outward shows of piety are meaningless.
