Luther

In virtue of this a Christian is called a new creature of God, which He Himself alone makes, above and besides all other creatures or works, yet in such a way that in this temporal life there is made but a beginning, and He works daily at it until it is perfected, when it will be a godly creature, pure and bright like the sun, without any sin and frailty, and all on fire with godly love.—Sermons, 1536
