Is Christianity a religion or something we have to work for?
Christianity is not a religion, nor is it something we work for. It is the new life in which the old sin nature is overcome, and it is accomplished entirely by the grace of God and by His power, and that alone.
Les explains that Romans chapter 6 deals with overcoming the old sin nature, old Adam, and entering into the new life, which is what Christianity is all about. He states plainly that it is not a religion and not just something we work for; it is something all accomplished by the grace of God and by His power, and that alone. The surrounding context says the old man, the old nature, old Adam, is crucified and had to be put to death, showing this new life is not achieved by human effort but by God's grace.
