John 6-8 (The Daily Walk Bible).
One of the most encouraging aspects of this reading is the reminder that, when we know God through Jesus Christ, we are His forever!
“I will never reject them.” (6:37)
“I should not lose even one of all those he has given me.” (6:39)
“Anyone who believes in me already has eternal life.” (6:47)
“Anyone who eats this bread will live forever.” (6:58)
We understand that Jesus is using an extended metaphor here, and he reveals that fact from the very beginning (6:35): “I am the bread of life. No one who comes to me will ever be hungry again. Those who believe in me will never thirst.” He is not talking physically, but spiritually. We still literally need to eat and drink, but spiritually we are satisfied once we believe! We have the same type of metaphor later as well (7:37): “If you are thirsty, come to me! If you believe in me, come and drink! For the Scriptures declare that rivers of living water will flow out from within!”
Regarding the woman caught in adultery: it is missing from just a handful of Greek manuscripts. It is in literally hundreds of other ones. I won’t get into the explanation of text types and manuscript transmission, but I will say this: why was it included here if not original? In fact, we can easily imagine Jesus coming to the temple, having this encounter, and then saying, as the sun is rising on the temple mount, “I am the light of the world!”
People are still trying to metaphorically “kill” Jesus for His claims. John leaves very little doubt that Jesus did indeed claim to be God. It’s as C.S. Lewis said: He’s either a liar, a lunatic, or Lord. It’s much easier to relegate him to the liar or lunatic category; it’s when you realize that He might actually be Lord that you have to actually deal with Him!
