Ephesians 1:7 and Grace Vs False Grace
Let’s point out two words in 1 John 1:9. These two words will be important for understanding what 1 John 1:9 is about. Pay attention to the word if in 1 John 1:9. “If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.” The word if introduces the verse. This, of course, introduces a conditional statement. Notice the word our? This word "our" (hémón), of course, means both the author (John) and his readers are addressed here. Keep these words in mind because we will now look at something Joseph Prince said about this verse.
Jesus said these profound words in Matthew 12:
John 10:4-5 says, “ And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice.  And a stranger will they not follow, but will flee from him: for they know not the voice of strangers.”
By saying that we have grace so that we never have to repent, these teachers are leading Christians into things that entice them to sin (skandalizó). They promise the Church liberty, but they themselves are the servants of corruption (phthora: i.e. destruction and moral decay). (See 2 Peter 2). They speak boastfully and excessively about grace and other topics, which results in spiritual bankruptcy because they don’t teach repentance from sin.
