We are exhorted throughout the Epistles to put on the new creation or new nature. When we come to the Lord, all we know is what we used to be, bound under Satan's power.
Many Christians continue to believe, even after salvation, that they are still like they used to be. They are men who look into the mirror of the Word, then go away and forget what they are as a new creation.
18. Question: What is one spiritual quality, you need not to forget?
(James 1:24)
