How can we know that God's Word is true? On what authority is Jesus's teaching compared to the rabbi's and teachers of His time? In John 7, Jesus attends the feast of tabernacles in Jerusalem under his own terms and timing, and when he reveals Himself he also claims that His authority is from the One who sent Him! And a good test of truth? If the words of a teacher bring glory to himself, then we need to be careful--but if those words bring glory to God, then they are trustworthy (v.18)!
