There happen to be very few books that claim to be God's plan for mankind. Many holy writings are no more than collections of inspired poetry, human wisdom, and disparate tales of gods. The Bible, with a history of Israel embedded in its text, is quite different from all other holy books.
The nearest claim comes from the Qur'an. The problem that arises when the two books are compared is that the Qur'an relies on the Bible for it's authority. IMO, the claims made by Muhammad do not stand up to scrutiny.
Many parts of The Bible do not stand up to scrutiny either. Easy examples are God realizing the Hebrews had it tough as slaves of the Egyptians, coming to their aid to free them from slavery, and then a few paragraphs later (literally) The Bible describes that the Hebrews themselves kept slaves. All hunky dory apparently. Or wait... no... that's a double standard if I have ever seen one. The 10 commandments are several parts junk. Jesus basically said nearly nothing of import in "The Beatitudes" at the Sermon on the Mount - just fluff and nonsense almost without directly calling on anything of substance. These things are directly put forth in The Bible as if they are profound and very serious matters. It is just plain strange.
The Bible points to one person as the hub around which history revolves, IMO. It points to Jesus Christ as the Saviour.
Let's remember you only a paragraph ago criticizing the Qur'an for "[relying] on The Bible for its authority". Christianty does the same thing... relying on Jewish texts. Jesus is YOUR add-on, exactly like Muhammad is the Islamic add-on. I see no difference in how these things played out. None.
Does knowledge of Jesus result in change? Of course, because to place faith in Christ means a change of personal direction. The scriptures say that a believer is 'new creation'. The old man is dead, and the new man is living for Christ.
The only thing I feel you have going for you here is that a person who markedly decides to turn their life in a different direction can do just that, and that it helps to have an "icon" to look to for inspiration. It also apparently helps to believe that someone is watching your every move. Otherwise, you can't literally tie any change that has happened in your life directly to the actual Jesus. You can't. The best you can do is tie the change to the ideas you have in your head about Jesus. That's all.
Another reason for accepting the Bible is the reality of the Holy Spirit.
Please demonstrate this reality. And believe me - it is gong to have to be something more than people speaking gibberish, people bowing their heads down on dirty carpet, people trying to push one another over during healing-prayer sessions, people falling on the ground and going into apoplectic fits, etc. That's just people being wacky. Demonstrate to me the
actual "Holy Spirit." Not the supposed effects on people who can't be trusted to even understand even the basest sort of a standard of evidence.
When the Gospel is preached with power, it brings the reality of God into the present. This happened to me when I was instantly healed following prayer in the name of Jesus.
Can you tell me what upon you was healed? Was it a
visible malady? Some wound that miraculously sealed up and disappeared? I've heard these types of things before, of course. You know, I was once in a congregation where whispers were going around that a person's missing finger grew back the night before at a prayer meeting they had held. This was basically all the rage (in whispers) among the parishioners present that morning. Then, when the pastor got up to talk to the crowd, do you know who he brought forward to demonstrate the results of the miraculous feats of healing that had gone on the night before? An older woman, bent in half sideways, physically unable to stand straight. And do you know what was supposedly "healed" the night before? Her back. How the people around me were just eating this crap up I have no idea. It was plain the woman
still had terrible problems with her back. If anything, the pastor should have been embarrassed to even claim that anything had been done in service to this woman by his "almighty" buddy in the sky. But no... belief trumps embarrassment, I have found. People are willing to do all sorts of things they should be patently ashamed of "in the name of God."
