I wanted to write you about our salvation, generally, but I need to contend for the faith against false teachers who pervert grace into sensuality and deny Jesus as Lord. Remember that Jesus destroyed Israelites who fell away after the Exodus, imprisoned the disobedient angels, and rained fire on Sodom. Like them, He will punish these false teachers. They irreverently blaspheme angels, like Cain, Balaam and Korah. Enoch and the apostles of Jesus prophesied their judgment. But you stay in Christ. Deal wisely with those partially taken in, being gentle or assertive.
God can present you faultless before Himself, through Jesus Christ. To Him be the glory!
