And I know that his commandment is life everlasting: whatever I speak therefore, even as the Father said to me, so I speak.
his.
John 6:63,68 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life…
John 17:3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
John 20:31 But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.
So I speak exactly what the Father has told Me to say.
This phrase highlights Jesus' obedience and submission to the Father's will, a recurring theme in the Gospel of John (John 5:19, John 8:28). Jesus' words are not His own but are given by the Father, indicating the unity and co-operation within the Trinity. This obedience is a model for believers, reflecting the call to live in accordance with God's will. The phrase also underscores the prophetic role of Jesus, as He speaks the words of God, similar to the prophets of the Old Testament who conveyed God's messages to the people (Deuteronomy 18:18). Jesus' teachings are thus authoritative and trustworthy, providing guidance and truth for those who follow Him. This connection to the Father’s words fulfills the messianic prophecies and establishes Jesus as the ultimate revelation of God to humanity.
Jesus speaks with settled certainty.
• He is not guessing about the Father’s will (John 8:28–29).
• His intimate knowledge flows from perfect unity with the Father (John 10:30).
• Because the Son knows, we can trust what He reveals (1 John 5:20).
God’s directive is not mere advice but the pathway to everlasting fellowship with Him.
• The command centers on believing in the Son (John 6:40; 3:16).
• Eternal life is both a present possession and future hope (John 17:3; Romans 6:23).
• Obedience to that command liberates from condemnation (John 5:24).
Jesus’ teaching flows directly from the Father’s heart.
• He never freelances; His doctrine is divine (John 7:16; 14:10).
• Speaking becomes an act of obedient love (John 4:34).
• What He says carries full heavenly authority (Hebrews 1:1–2).
Precision matters; every word is intentional.
• The Son transmits the Father’s message without alteration (John 12:49; 14:24).
• This fidelity models how God’s servants should handle His word (Jeremiah 1:7; 1 Peter 4:11).
• Because Christ’s words are the Father’s, rejecting them is rejecting God Himself (John 5:38; 8:47).
Jesus knows with certainty that the Father’s command faith in the Son brings eternal life. Confident in that truth, He speaks only what the Father entrusts to Him, ensuring that every syllable carries divine authority and life-giving power.
(50) And I know that his commandment is life everlasting.--i.e., the commission of the Messianic work. It is better to read here, as before, eternal life. (Comp. John 3:15, et al.) The Son speaks not of Himself, but He speaks as executing this commission, which brings spiritual and eternal life to the world. It could not be otherwise. This commandment being eternal life, the whole teaching of the Messiah must simply be an utterance of it.As the Father said unto me, so I speak.--This clause answers to "what I should say and what I should speak" in the last verse. The external revelation is regarded as the work of the Son. That which the Father says is the truth revealed, and the matter and form are here identified.
