In John 7, Jesus teaches boldly in the temple, revealing why some people struggle to hear God's voice while others embrace it. The Jewish leaders questioned His wisdom despite His lack of formal training, but Jesus explained that His teaching came directly from the Father. The key to understanding God's truth isn't intellectual capacity but willingness to obey. Those who genuinely want to do God's will can discern His voice, while those who resist His authority remain spiritually deaf. Jesus contrasts Abraham's receptive heart with King Saul's closed heart, showing that humility and surrender are essential for hearing from God.
