James 1:22 Do not merely listen to the word, and so deceive yourselves. Do what it says. 23 Anyone who listens to the word but does not do what it says is like someone who looks at his face in a mirror 24 and, after looking at himself, goes away and immediately forgets what he looks like. 25 But whoever looks intently into the perfect law that gives freedom, and continues in it—not forgetting what they have heard, but doing it—they will be blessed in what they do.
1 Corinthians 13:12 For now we see only a reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known.
Ecclesiates 1:2d; 12:8c "All is vanity"
