Romans 1:26-27:

For this cause God gave them up to vile affections: for even their women did change the natural use into that which is against nature:
And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompense of their error which was meet.

Notes on Romans 1:26-27:

This passage is as true as it ever was, despite its unpopularity among the “politically correct” crowd and ministerial cowards who will not make a bold public stand for biblical truth.  (Some like to “avoid controversy,” which they indeed do; they also avoid pleasing God.)  This is part of the New Testament, so please don’t call yourself a Full Gospel pastor if you never preach it.  You don’t have to ride it like a hobbyhorse, but most pastors shy away from ever proclaiming this part of the truth due to the fear of man, which brings a snare (Proverbs 29:25).  I have made bold public stands on this issue in Maine (where I lived and pastored for many years), and the owner of the two local newspapers printed attack articles against me, telling everyone to get away from me and my church.  He refused to print my letters in response and he would never print my press releases either.  (No one left because of him, by the way, and they were his papers, so he had the right to express any opinion he wanted and filter news as he saw fit.)  But that never stopped me.  Persecution is part of living godly in Christ Jesus (2 Timothy 3:12).

How are people going to get set free from what this passage describes as a vile, unnatural, erroneous, lustful, disease-breeding lifestyle if no one tells them that it’s wrong, let alone that there is Someone who wants to set them free?  The devil has been very busy telling everyone, especially schoolchildren, that various forms of immorality are to be celebrated.  If we clam up, that is the ONLY side they will hear.  People who engage in these practices are sinners for whom Christ died.  How can we not tell them that there is a better way and let them know the plan of salvation?  Some people in Corinth were homosexuals before they were saved (1 Corinthians 6:9-11), so sexually immoral people are certainly not beyond God’s loving reach.
