Dr. Frederick K.C. Price teaches that believers must test spiritual influences rather than assume all supernatural activity is from God, drawing from 1 John 4. He warns that Satan uses counterfeits, showing that signs or good results are not proof of truth unless they exalt Jesus Christ, with the key test being a confession that Jesus came in the flesh. The message reassures believers that they have already overcome deceptive spirits through God’s greater power and must uphold scriptural standards to avoid spiritual deception.
