What does the Bible say about how sinners know the doctrine of God?

In John 7:17, Jesus explains that if anyone is willing to do the will of God, they will know whether the doctrine He teaches is truly from God or merely of man's making. This emphasizes the sovereignty of God in salvation; those chosen by God to believe will be willing to come to Christ as humble sinners. It reflects the transforming work of the Holy Spirit in the believer's heart, opening their eyes to the truth of the gospel, demonstrating that knowledge of doctrine is intimately related to submission to God's will.
