The Spirit of God who comes to Us
1 Corinthians 2:12 (ESV) … “Now we have received not the spirit of the world, but the Spirit who is from God, that we might understand the things freely given us by God.”
The importance of Paul’s analogy becomes clear in his affirmation that he and the Corinthian believers had not come to Christ under the influence of the spirit of the world. No mere earthly wisdom brought the Corinthians to the gospel of Christ. The Spirit who is from God did this for them. The Spirit of God comes upon all who believe in Christ (Rom. 8:9) and reveals to them the mind of God.
For what purpose does the Spirit of God come to those who believe? He comes in order that they may understand what God has freely given. Christians cannot understand the wonder of all they have received from God by observing things with their natural eyes. God freely gives the salvation that culminates in their blessings with Christ in the new heavens and new earth. The Holy Spirit enables them to see the wonder of this gift as well as the wisdom that leads to it.
