Renewal vs Reformation

A friend pointed out to me that man will reform (change into an improved condition) people, but God RENEWS (to make like new: restore freshness, vigor, perfection). It's an important difference. I've heard many praying for reformation in the church when what we really need to be praying for is renewal. 

“Modern Christians hope to save the world by being like it, but it will never work. The church’s power over the world springs out of her unlikeness to it, never from her integration into it.” A.W. Tozer

Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come. 2 Corinthians 5:17
