I found this great quote about what the gospel is meant to do to our opinions of ourselves from Tim Keller on “theocentricview“:
“The Christian gospel is that I am so flawed that Jesus had to die for me, yet I am so loved and valued that Jesus was glad to die for me. This leads to deep humility and deep confidence at the same time. It undermines both swaggering and sniveling. I cannot feel superior to anyone, and yet I have nothing to prove to anyone. I do not think more of myself nor less of myself. Instead, I think of myself less.”
