How do we know Jesus is the true source of life?

Throughout the Gospel of John, Jesus speaks with an authority unmatched by any other teacher of His time, as highlighted when the officers sent to arrest Him return empty-handed, stating, 'Never man spake like this man' (John 7:46). This demonstrates that His teachings resonate deeply with those who hear Him, revealing His divine nature and their need for Him as the source of life. The Reformed faith asserts that it is in Christ alone, through His effectual calling and grace, that we find salvation and eternal life. The impact of His words on the hearts of His listeners is a testament to His divine authority.
