I John 4:1
Dear friends, do not believe every spirit, but test the spirits to see whether they are from God because many false prophets have gone out into the world.
The Bible makes it clear that we are to walk carefully in the spirit realm. The reason for this is that there are deceivers out there who will take advantage of those who do not discern what is really true and what is false. You see we are accountable for what we believe personally and for what we teach to those who are under our spiritual umbrella.
It is also important to note that all that sounds Christian may not be so. I have had people who had a real zeal for God come to me and sing the praises of a person or group based on what they heard them say. Just because God is mentioned or the Bible is quoted, does not mean that this is a Christian man, woman or organization. Remember that the Bible also says that Satan is a deceiver and that he and his ambassadors parade around as “angels of light”. The Bible also says that just because someone says that they believe in God is not enough to prove that they really know God. In fact, it says that just because you believe in God doesn’t make you a Christian. James 2:19 tells us that the devils believe and tremble. Does this make them saved devils? Of course not, it only means that they have an intellectual knowledge of God. There are many who have this same type of knowledge that are teaching and even preaching, yet what they say is not from the Holy Spirit but from either man’s wisdom or directly from the devil himself.
For this reason, it is so necessary for us to walk in and discern in the Spirit. Do not be fooled by those who just claim to know God, test the spirits to be sure.
