The Christian gospel is a message of liberation to those who are enslaved by sin. In our presentation of the gospel we must not stop with forgiveness because as wonderful as that is, Jesus not only promises to forgive our sins, but to set us free from the power of sin. Even though our experience of complete liberation from sin, and from death which is inevitably attached to it, awaits the new heaven and earth, here and now, in this life, there is power to live a life of faith and repentance in the Lord
This profound experience of liberation with the promise of complete liberation to come should make Christians sensitive to forms of human slavery that exist in our world today and we should be willing to do what we can to break the bonds of those who are oppressed by cruel and immoral masters.
