21. “Jesus had already mentioned His leaving them (John 7:34), but the Jews had misunderstood what He said.” (Wiersbe, Warren W, The Bible Exposition Commentary New Testament Volume 1 Matthew-Galatians. [Colorado Springs: David C Cook, 2004], 321)
“One inescapable truth jumps at us from these verses: the heresy that everyone will be saved some day denies the clear teaching of the Bible. There will be no escape for those who refuse the gospel—not in the first century and not today. Three times Jesus warned them, you will die in your sins (vv. 21,24).” [Max Anders and Kenneth O. Gangel (2012). HNTC Vol. 04: John. B&H Publishing Group. Retrieved from https://read.lifeway.com]
“The use of the singular ‘sin’ here probably is a condemnation on their unwillingness to believe, but the repetition in the plural (sins) at 8:24 means that Jesus rendered his verdict on their evil actions as well.” (Borchert, Gerald L., The New American Commentary Volume 25A, John 1-11. [Broadman & Holman Publishers, 2002], 299)
22. “Jewish tradition condemned suicide as a particularly heinous sin that resulted in permanent banishment to the worst part of Hades (Josephus, Jewish Wars, iii.viii.5 [iii.375]). God did deliver Him to be killed (Acts 2:23); thus, as God, He gave up His own life (10:18).” (MacArthur, John, The MacArthur Bible Commentary. [Nashville, Thomas Nelson Inc., 2005], 1385)
Not of this World
23. “It was they who were going to the place of judgment! Jesus was returning to His Father in heaven, and nobody can go there who has not trusted the Savior.” (Wiersbe, 321)
24.” Jesus emphasized that the fatal, unforgivable, and eternal sin is failure to believe in Him as Messiah and Son of God.” (MacArthur, 1384)
25. Jesus “had given them every evidence that He is the Son of God, yet they deliberately rejected the evidence.” (Wiersbe, 321)
26. “Our Lord always maintained that what He was doing and saying was what the Father wanted Him to do and say. He claimed that God the Father had sent Him and that He was doing the Father’s will. He never appealed to His own mind or His own intellect.” (McGee, J. Vernon, Thru the Bible: Volume IV: [Nashville: Thomas Nelson, 1983], 418)
“Jesus boldly made several claims to deity. He said He would judge, and judgment (to the Jews) belonged only to God. He claimed to be sent by God, and He claimed to have heard from God the things that He taught.” (Wiersbe. 321)
27. “They missed the whole point. They are of the earth; they do not understand heavenly things.” (McGee, 418)
28. “The phrase lifted up the Son of Man refers to the way a body was placed on the cross and the cross elevated in public on a hill of execution. Often we pray that Jesus will be ‘lifted up’ meaning we wish him to be exalted and glorified. But in John this terminology distinctly refers to the cross.” [Max Anders and Kenneth O. Gangel (2012). HNTC Vol. 04: John. B&H Publishing Group. Retrieved from https://read.lifeway.com]
“The concept of ‘lifted up’ (hypsoun) in John is the way Jesus referred to the events involved in his glorification (cf. 3:14; 12:32-34), an expression used to identify his work on earth as the sacrificial lamb of God who died on the cross and was raised up in victory so that all who believe might have life (cf. the important combination in Isa 52:13 wherein hypsoun and doxazein, ‘glorify’ both appear)” (Borchert, 300).
29. “Not only was He sent by the Father, but the Father was with Him because He always did what pleased the Father.” (Wiersbe, 322)
30. “Some of the listeners put their faith in Him.” (Wiersbe, 322)
“Salvation is a matter of life or death. People who live in their sins and reject the Savior must die in their sins…We either receive salvation by grace or experience condemnation under God’s law. We either walk in the light and have eternal life, or walk in the darkness and experience eternal death.” (Wiersbe, 322)
