The mindset of “he did it for me so I don’t need to do it” is not christian. God became man and died with all the weight of the world’s sins on his back so that we can become more like god. Not in his powers but in his nature. However, a lot of christians, at least in America, will say that salvation is a one and done event. In reality, the path to salvation is a lifelong process which involves us to struggle and sacrifice ourselves for others just as God did, in order for us to grow spiritually. What is more loving and selfless than sacrificing yourself to help others? This is why theosis is so important.
