Note 3 at Acts 10:38: In this verse Peter is giving a very brief and yet very descriptive summary of the life and ministry of Jesus. Jesus was anointed with power and with the Holy Ghost. He used this power to do good, not evil. This is one of the main characteristics of God and is one of the easiest ways to discern what is from God and what is from the devil. God is a good God and the devil is a bad devil. If it's bad it's from the devil. If it's good it's from God (see note 5 at Jn. 10:10, p. 301).

Jesus healed all that were oppressed of the devil. Therefore, Jesus showed us the perfect will of the Father by healing all (see note 1 at Mt. 8:16, p. 119). This verse also says they "were oppressed of the devil" (see note 3 at Mk. 1:32, p. 119), not of God. God is not the one who brings sickness. It's the devil, and he does it only to steal, kill, and destroy (Jn. 10:10).
