As the apostle Paul writes to the church in Corinth concerning the wisdom of God, and to the church in Rome concerning the bondage of sin, we are told of one who is able to release us from that sin. Rather than the foolishness of men, God uses his Holy Spirit in the salvation of his people.
For God the Holy Spirit inspires the Scriptures. Only God knows the mind of God. Through the Scriptures, we can know the will of God. Any serious look into the Scriptures will reveal a canon which, although inspired by God through 40 different men over a period of around 1500 years, is consistent throughout.
Yet, even with the Scriptures and the weight of evidence in their favour, our minds resist God’s will. Our sinful natures are enslaved by that sin and are constrained to go against God’s will. The Spirit illuminates our minds that we may turn to God. If any of us have already turned to God, it is not because we are any smarter than others, or any other reason within ourselves, but because of the Spirit working in us. However, once the Spirit enables us to turn to God, we will turn to God freely.
He changes us from within, for only with a changed heart can we truly do the will of God. He will sanctify us, slowly conforming us to the image of God the Son, slowly being made holy. We will desire to know God’s will and will want to carry it out, he reveals the will of God through his word. He enables us to understand and in so doing, be able to glorify our Creator.
