This sermon examines the testimony of Jesus in John 5, where He presents multiple witnesses to His divine identity, including John the Baptist, His miracles, the Father, and the Scriptures. The central argument posits that the rejection of Jesus by religious leaders is not due to a lack of evidence, but rather a deliberate unwillingness to submit to Him. The preacher contrasts the temporary joy of enjoying a preacher's light with the necessity of coming to Christ for eternal life, highlighting the human tendency to seek human glory over divine truth. By analyzing the 'autopsy' of unbelief, the message reveals that the root of rejection is a lack of love for God and a desire for self-justification. The sermon concludes with a call to repentance, asserting that while humans are naturally unwilling to come to Christ, God's grace transforms hearts, making the unwilling willing through His power.
