How can we tell the true Spirit of God from false spirits that pretend to be the Spirit of God. The true Spirit of God will indwell a person who repents and calls upon Jesus to be his or her Savior. A false spirit can not do that. The true Spirit will emphasize Jesus and His sacrifice. A false spirit will speak of himself. The true Spirit will lead people to forsake the things of this world and seek the things above where Christ sits on the right hand of God. The false spirit will lead people to seek the material things of this world and position and fame. The true Spirit will lead Christians to be respectful and considerate of others. The false spirit will cause people to be rude and arrogant. The true Spirit will led people to respect and accept the obvious literal interpretation of scripture. The false spirit will led people to reject truth that they do not like and strive to manipulate scripture. Maybe others can find some differences between the Spirit of God and the spirit of Satan.
