The final Church before Jesus' return will be without "spot or wrinkle", which refers to bondage in sin and spiritual oppression (by the spiritual enemies of the Lord on His servants).
Ephesians 5:26-27
"to make her holy, cleansing[a] her by the washing with water through the word, and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless."
