When someone denies the Trinity, the Deity of the Holy Spirit, salvation by grace through faith apart from works and the assurance we HAVE been given so that we can KNOW we are redeemed and have eternal life, I think it’s wise to consider the source of such blasphemy and rebuke it. Also, praying for those who are thus deceived helps as well, though God will not force Himself upon those who refuse to receive the knowledge of the truth that they might be saved. Who knows how much time we have left.
I agree. And we need point out the errors lest others fall for the deceit.
