<p>4:19 <i>Who being past feeling gave themselves up to sensuality, to work all uncleanness with greediness</i>- As noted on :18, this language refers to those who leave one way of life for another, rather than those who had never known the way of righteousness. The Lord gave Himself over for us on the cross (s.w. 5:2,25), but in response, these people had given themselves over to pleasing the flesh. The sensuality in view was provoked by the false teachings of :14. These teachings turned God's grace into sensuality (Jude 4); the words of these false teachers allured believers into sensuality (2 Pet. 2:18). So it was not simply a case of believers falling for the temptation to live the life of the world; the false teachers were encouraging the converts to engage in the sensual practices of idol worship in the name of serving the Lord Jesus. This was the problem at Corinth and was widespread; the false teachings were attractive because they enabled believers to live the life of unbelievers whilst still thinking they were within the body of Christ.</p>
