Galatians 1:8 But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed. (Hmmm, I heard a story about some guy and his angel friend moroni telling a different gospel. Sad people believe that story instead of taking heed to this clear warning from the scriptures. Fortunately God loves misled people as much as any other and desires their repentance just like the rest of us.)
2 Timothy 4: 3-4 For the time will come when they will not endure sound doctrine, but according to their own desires, because they have itching ears, they will heap up for themselves teachers; and they will turn their ears away from the truth, and be turned aside to fables.
Ephesians 4:18-19 having their understanding darkened, being alienated from the life of God, because of the ignorance that is in them, because of the blindness of their heart; who, being past feeling, have given themselves over to lewdness, to work all uncleanness with greediness. (Boy isn't that about the truth. Between some slippery church leaders, politicians, and activists wanting the right to do any vile thing, these verses pretty much describe modern America)
Galatians 5:19-21 NIV The acts of the sinful nature are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God. (Note: This was written as a warning to people in the church.)
Jeremiah 23:1-4 "Woe to the shepherds who destroy and scatter the sheep of My pasture!" says the Lord. Therefore thus says the Lord God of Israel against the shepherds who feed My people: "You have scattered My flock, driven them away, and not attended to them. Behold, I will attend to you for the evil of your doings," says the Lord. "But I will gather the remnant of My flock out of all countries where I have driven them, and bring them back to their folds; and they shall be fruitful and increase. I will set up shepherds over them who will feed them; and they shall fear no more, nor be dismayed, nor shall they be lacking," says the Lord.
Revelation 22:18 For I testify to everyone who hears the words of the prophecy of this book: If anyone adds to these things, God will add to him the plagues that are written in this book;
Revelation 22:19 and if anyone takes away from the words of the book of this prophecy, God shall take away his part from the Book of Life, from the holy city, and from the things which are written in this book.
