“The Great Commission would be a futile task if the ultimate power and authority lay in our hands or in the hands of those to whom we bring the gospel. Jesus Christ did not make it possible for us to be saved. He did not begin a work of redemption. He did not do ‘his part’ so that we could do ours. Rather, Jesus Christ accomplished everything. He assumed our flesh. He has fulfilled all righteousness in our place and has borne the judgment for every one of our sins as our substitute. And he has been raised as the firstfruits of the whole harvest, the beginning of the resurrection from the dead. There is no more redeeming work to be done!” — Michael Horton in his book
