I’m listening to this message as I write and can tell you its one link I am sending to my friends. Its a very good message. God bless men like John Piper who teach the truth…there are so few left today.
The urgency of this topic is underlined in Galatians 1:6-9:
I am astonished that you are so quickly deserting him who called you in the grace of Christ and are turning to a different gospel—7 not that there is another one [there is no other gospel], but there are some who trouble you and want to distort the gospel of Christ [there is a distortion that becomes another gospel] 8 But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. [The fixedness of the gospel could not be expressed more strongly] 9 As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed [Not just believing a different gospel but advocating for it brings a final curse—1 Corinthians 16:22 – If anyone has no love for the Lord, let him be accursed. Our Lord, come!]
