If we are humble, if we are diligent in the service of the Lord, if we seek to serve him with an eye single to the glory of our Father in heaven (keeping in mind that he has asked for that service with a full heart, with all our might, with all our mind, and with all our strength), we will not go astray. We will not be seduced by evil spirits nor by the spirits of men, but we will be led and directed by the Spirit of God.
