In Christian teaching freedom can have a number of different connotations. Free will and freedom from sin are two important areas to discuss in the context of freedom isn't free."
It is believed that God grants his followers free will to make their own choices. The idea of predestination and karma are not accepted in the Christian church. While believers are given this free will, it does not come without costs. Christians are expected to live lives of service and gratitude and follow God's commandments. Christians believe that free will comes with a great responsibility to make moral decisions.
The ultimate freedom that Christians celebrate is freedom from sin and the ability to enter heaven upon death. This freedom was not free, according to Christians. Adherents believe that Jesus died to free the world from original sin and allow Christians to enter heaven. With this in mind, freedom was and is not free.
