The concept of substitution lies at the heart of both sin and salvation. For the essence of sin is man substituting himself for God, while the essence of salvation is God substituting himself for man.
John Stott[Christian rebellion] arises from the doctrine of mankind made in the image of God, and therefore protests against all forms of dehumanization. It sets itself against the social injustices which insult God the Creator, seeks to protect human beings from oppression and longs to liberate themโฆ it protests against every authoritarian regime, whether of the left or of the right, which discriminates against minorities, denies people their civil rights, forbids the free expression of opinions or imprisons people for their views alone.
