What was the power behind Jesus' ministry? Some critics say it was deception. Some skeptics say it was people's imagination. Some even attributed his power to demons and the devil. It's one thing to disbelieve. It's another to believe in spiritual power and then attribute Jesus' spiritual power to the evil one. Jesus had great power. So where did he get that power? He got it from his identity as the Son of God. He referred to this source of power as the Holy Spirit — the Holy Spirit that would be present in the heart of everyone who is a true believer in him. This power is holy, from God, and a manifestation of God's very real presence. To assign this power to the source of evil is to blaspheme and cut ourselves off from our only true source of power, grace, and forgiveness!
