Personally, I had never heard of this woman before I read the following pdf. When one does a google search there is more than enough info on this woman for a person to know she is a false teacher. One of the churches she is listed to speak in has this bio on her. It says “Author / Speaker, Kat Kerr will challenge what you have believed about Heaven, the “other” dimension (spirit realm), this life, death and even eternity. Since 1996 she has been ‘caught up’ by the Spirit of God and taken on amazing journeys into the Third Heaven as well as to Hell. She lives and moves in the supernatural which gives her a detailed understanding of how God, His angels and even darkness operate today. You will feel the manifest presence of God as she shares what it is like to stand before the living God in the Throne Room. The Father has given hard evidence in her Revealing Heaven series that proves Heaven truly exists and that you will live a literal life there.”
There is a lot to unload in that bio but I will leave that to you to do. Remember what God’s Word says in 1Timothy 2: 11-13 Let the woman learn in silence with all subjection. 12 But I suffer not a woman to teach, nor to usurp authority over the man, but to be in silence. 13 For Adam was first formed, then Eve. and Revelation 2:20 Notwithstanding I have a few things against thee, because thou sufferest that woman Jezebel, which calleth herself a prophetess, to teach and to seduce my servants to commit fornication, and to eat things sacrificed unto idols.
