Yet Bible writer named John was so careless that he could produce a verse that is inherently contradicting itself: “No one has ascended into heaven except he who descended from heaven, the Son of Man.”
Ireneus, With due respect, I feel you are again taking things out of context and are also isolating sentences from conversations.
You have missed an important word from John 3:13, and that is the verse begins with 'and'. The verse is a part of the conversation that Jesus was having with Nicodemus. (verses 10-31).
Why did Jesus tell this verse? To comprehend Jesus's words you need to understand the entire conversation. In the entire conversation from verse 10, Jesus was talking about his authority as being the only person who had been with God in his prehuman existence and had the knowledge to teach people about heavenly things. No other person was in that position because no one had been with God there.
Had any human in the Bible gone to heaven and then come down from heaven and taught people about the kingdom of God? No. Only Jesus. So when he told that only he had ascended to heaven, it meant that only he was the one who had been in Heaven earlier and thus can now teach people about the kingdom of the heavens. That's the way we humans use certain semantics.
"ascended to heaven" cannot always mean physically going to or raised to heaven. You cannot take it in a literal sense if the context does not warrant. Let me give you an example:
Take the following three sentences:
1. I went to a musical concert yesterday, and wow, I should say that her performance was out of this world!
2. I went to Jane's house for a party and Kim drank until he was out of this world.
3. After seeing the first rocket launch, my 99-year-old grandpa excitedly exclaimed, "O Man, no one could imagine we can send such a huge thing out of this world"
Will you take the phrase "out of this world" in its literal sense in all the sentences?
in the above three sentences, the phrase "out of this world" means three different things in each instance, first sentence. it denotes extraordinary performance, the second sentence refers to intoxication and third means sending out in space.
It's about semantics. An effort is needed to understand it rather than simply discrediting it as contradictory.
