John's Knowledge of the Sanhedrin's Discussion in John 11
The question of how John knew what was said between the religious leaders at the end of John 11 is one that addresses the nature of biblical inspiration and the role of the Holy Spirit in guiding the authors of Scripture. Paul writes in Romans 8:28 that God works all things together for the good of those who love Him, and this includes the recording of historical events in the Bible. It is likely that John, as an apostle, had access to information about the discussions among the religious leaders through his connections with other believers or even through direct revelation from the Holy Spirit.
This truth highlights the sovereignty of God in the writing of Scripture, where human authors were guided by the Spirit to record events and teachings that would be beneficial for the church. The fact that John was able to include such details in his Gospel demonstrates the sufficiency of Scripture, which provides a reliable and trustworthy account of the life, death, and resurrection of Jesus Christ.
The gospel connection in this event is that Jesus' raising of Lazarus from the dead led to increased opposition from the religious leaders, ultimately culminating in His crucifixion, which was a necessary step in the plan of salvation. This truth points to the heart of the gospel, where God's sovereignty and human responsibility intersect, and where the glory of God is revealed through the person and work of Jesus Christ.
