People should know that false teachers will teach anything they believe, and not from the Bible. People also should look at the preachers their behaviour and see if they have the Holy Spirit in them, following, living according and teaching the words of the Holy Bible. Often their way of talking, using a language which is not according the way Jesus would talk shall dismantle them and should be a sign for you that they are not the right one to follow.
When men let their faith and confidence in the credibility of the Word of God get away from them, there is danger of lowering their ethical standard. A tottering faith in the Bible narratives shall bring morality to be unstable and to stagger also. When there is a rejection of the integrity of the Old Testament narratives there shall be no vibration to come to see the truth of this life and the person shall move or sway unsteadily or unsure in this materialist world were more and more people are moving away from God and are having their egoism being the base of their life disturbing their relationships, making them unstable.
