God is quite specific that His people shall have nothing to do with sorcerers or witchcraft or people who practice spells. These practices are detestable to the Lord. And I believe that is because they take the emphasis off God as the author and finisher of our faith.
When you seek our someone to tell the future, you are essentially saying that you don't believe that God is big enough to hold the future. That you don't trust Him to make provision for you. That He is not the most important thing in your life.
And that smacks again of idolatry.
The only spirit we need to seek is the Holy Spirit. All other spirits lead to the devil. They are his counterfeit of the Holy Spirit, poor imitations of the real thing.
The Holy Spirit is one person of the Triune God. He is the Paraclete, the comforter that Jesus promised His disciples. He is the portion of God that can live within us when we become His children. His presence in our lives keeps us connected with the power and will of God.
If God is the power source and we are the lightbulbs, the Holy Spirit is the wire that connects us. No other spirit can connect us with God's power. Why should we settle for a line that goes nowhere?
Keep us ever mindful that You are the Alpha and Omega, that all knowledge and truth resides in You, that there is no truth or knowledge outside of You.
In Jesus' most precious name.
