Why is it important to know truth? What is truth? We know truth is a not something, it is someone. Jesus is truth. Knowing the truth gives us victory over the fiery darts of deception. The war against the devil is fought by the Holy Spirit within us. The Holy Spirit causes us to be intimately involved with the one who is truth. As we interact with the Holy Spirit He fights in us and through us. We cannot fight in our own strength. The Battle is the Lord's!
