12 What we have received is not the spirit of the world, but the Spirit who is from God, so that we may understand what God has freely given us. 13 This is what we speak, not in words taught us by human wisdom but in words taught by the Spirit, explaining spiritual realities with Spirit-taught words. 14 The person without the Spirit does not accept the things that come from the Spirit of God but considers them foolishness, and cannot understand them because they are discerned only through the Spirit.—1 Cor. 2:12-14 NIV
We are born with the spirit of the world in us which causes us to sin. When we accept Jesus as our Savior, we receive God the Holy Spirit. He comes to abide in us and to lead us into all truth. To understand the truth takes wisdom from heaven. This can only be taught by the Holy Spirit who teaches us spiritual realities with Spiritual words. If we have not received the Holy Spirit, we will not accept the truths that He wants to teach us. The person who has not received the Spirit of God cannot discern or understand Spiritual things. That person considers Spiritual things to be foolish because of his or her lack of understanding. Those who have truly accepted Jesus as their Savior are Spirit-bred, Spirit-fed and Spirit-led!
6 Flesh gives birth to flesh, but the Spirit gives birth to spirit. 7 You should not be surprised at my saying, ‘You must be born again.’—John 3:6 NIV
