Jesus’ Statement in Context

“​Not that I accept human testimony; but I say these things so that you may be saved.” (John 5:34)


Direct Promises from Jesus in the Gospel of John

John 3:16 — “For God so loved the world that He gave His one and only Son, that everyone who believes in Him shall not perish but have eternal life.”

John 6:40 — “My Father’s will is that everyone who looks to the Son and believes in Him shall have eternal life, and I will raise him up at the last day.”

John 6:47 — “Truly, truly, I tell you, he who believes has eternal life.”

John 10:27-28 — “My sheep listen to My voice; I know them, and they follow Me. I give them eternal life, and they will never perish. No one can snatch them out of My hand.”

John 14:2-3 — “In My Father’s house are many rooms… I am going there to prepare a place for you… I will come back and welcome you into My presence.”

John 17:3 — “Now this is eternal life: that they may know You, the only true God, and Jesus Christ, whom You have sent.”


Supporting Testimony from the Epistles

1 John 2:25 — “And this is the promise that He Himself gave us: eternal life.”

1 John 5:11-13 — “And this is that testimony: God has given us eternal life, and this life is in His Son… I have written these things to you who believe in the name of the Son of God so that you may know that you have eternal life.”

Titus 1:2 — “in the hope of eternal life, which God, who cannot lie, promised before time began.”

2 Timothy 1:10 — “our Savior, Christ Jesus… has abolished death and illuminated the way to life and immortality through the gospel.”

Hebrews 6:18 — “so that by two unchangeable things, in which it is impossible for God to lie, we… may be strongly encouraged.”


Additional Witnesses That Underscore His Reliability

Revelation 1:18 — “I am the Living One; I was dead, and behold, I am alive forever and ever! And I hold the keys of Death and of Hades.”

Acts 4:12 — “Salvation exists in no one else, for there is no other name under heaven given to men by which we must be saved.”

1 Peter 1:3-4 — “According to His great mercy He has given us new birth into a living hope through the resurrection of Jesus Christ from the dead, and into an inheritance that is imperishable, undefiled, and unfading, reserved in heaven for you.”


Putting It All Together

• Jesus repeatedly anchors eternal life in Himself—His word, His work on the cross, and His resurrection.

• The Father, the apostles, and the written Word consistently echo and confirm that promise.

• Because God “cannot lie” (Titus 1:2) and it is “impossible for God to lie” (Hebrews 6:18), every promise Jesus makes about eternal life is utterly dependable.
