Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world. By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God and every spirit that does not confess Jesus is not from God. This is the spirit of the antichrist, which you heard was coming and now is in the world already. Little children, you are from God and have overcome them, for He who is in you is greater than he who is in the world. They are from the world; therefore they speak from the world and the world listens to them. We are from God. Whoever knows God listens to us; whoever is not from God does not listen to us. By this we know the Spirit of truth and the spirit of error. 1 John 4:1-6
There are two spirits working here on earth, the Spirit of truth and the spirit of error. No error comes from the Spirit of God, naturally the devil has been wrong for a long time. You need to be able to know which one is right and which is not, as we have been told how to test them. It is very important that we do so effectively and accurately according to the instructions God gave us, as this will finally differentiate them. God’s Spirit will let you test Him, because He won’t go against God’s instructions. God gave us the authority to test them all to see who’s telling the truth, and who’s lying, so use this authority to your advantage. If the Spirit of God is your final authority, there is not much the others can do to harm you.
We are from God, and if the Spirit is from God, He will listen to you without question, as long as your instruction is from God, He will not fight against you, He will help you. Not so for the spirit of error, there will be chaos the moment you open your mouth to test or face him. Because the Spirit of God is in unity with Him, He will not fight against what belongs to God. Test the spirits and see if they are of God or not. After you have tested them and found out that they are not of God, draw near to God, resist that spirit and he will flee from you. If the test shows that the spirit is of God, humble yourself and He will lift you up. God bless you with the gift of His Holy Spirit just as He gave to His Son (Mark 1:27) so you will have this authority and power you need to overcome all the others. Let it be so.
