Scriptures Referenced in This Episode:
“There used to be false prophets among God’s people, just as you will have some false teachers in your group. They will secretly teach things that are wrong—teachings that will cause people to be lost. They will even refuse to accept the Master, Jesus, who bought their freedom. So they will bring quick ruin on themselves. Many will follow their evil ways and say evil things about the way of truth.” 2 Peter 2:1-2 (NCV)
“The time will come when people will not listen to the true teaching but will find many more teachers who please them by saying the things they want to hear. They will stop listening to the truth and will begin to follow false stories.” 2 Timothy 4:3-4 (NCV)
“...The Bereans were eager to hear what Paul and Silas said and studied the Scriptures every day to find out if these things were true.” Acts 17:11b (NCV)
“Really, there is no other Good News. But some people are confusing you; they want to change the Good News of Christ. We preached to you the Good News. So if we ourselves, or even an angel from heaven, should preach to you something different, we should be judged guilty! I said this before, and now I say it again: You have already accepted the Good News. If anyone is preaching something different to you, let that person be judged guilty!” Galatians 1:7-9 (NCV)
“Let the teaching of Christ live in you richly. Use all wisdom to teach and instruct each other by singing psalms, hymns, and spiritual songs with thankfulness in your hearts to God.” Colossians 3:16 (NCV)
