I think in agreement with you, it is important - reasonable - to use logic and reason with evidence based faith. Apparently though, there is a difference between the opinions of millions of "Christians".
Whereas some think they have good reason to believe the Bible contains contradictions, some think they have good reason to believe the Bible contains no contradiction - only what appears that way, due to
perhaps in some cases, one's viewpoint, or understanding.
While some think they have good reason to believe they "really have no way of knowing whether it's all the "Word of God" all the word of Man (literally, just men 40+ of them!), or a combination of both", some believe they have solid evidence that what the apostles Paul and Peter said, is 100% true, when they said...
(2 Timothy 3:16, 17)
16 All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness, 17 so that the man of God may be fully competent, completely equipped for every good work. . .
(2 Peter 1:20, 21)
20 For you know this first, that no prophecy of Scripture springs from any private interpretation. 21 For prophecy was at no time brought by man’s will, but men spoke from God as they were moved by holy spirit.
So contrary to the view of some who doubt the truthfulness and reliability of scripture, many millions have used reason (soundness of mind) and their thinking ability, to conclude that the Bible is truly "the word of God, and they are able to solidly stand behind that conclusion.
The practice of divination is different to looking to the creator of the universe - the grand instructor - for direction, guidance, knowledge, understanding and wisdom.
According to the Bible, God reveals - according to his own will - what man needs to know.
Apparently this is different to one using tarot cards and other means, in order to acquire knowledge.
However, for one who does not trust the Bible, it is quite obvious they would look to other means, and what else would we expect they will turn to, but divination - spiritism?
The Bible reveals this throughout.
Divination -
Source
Practitioners of divination believe that superhuman gods reveal the future to those trained to read and interpret certain signs and omens, which, they say, are communicated in various ways: By celestial phenomena (the position and movement of stars and planets, eclipses, meteors), by terrestrial physical forces (wind, storms, fire), by behavior of creatures (howling of dogs, flight of birds, movement of snakes), by patterns of tea leaves in cups, by oil configurations on water, by the direction falling arrows take, by the appearance of body parts of sacrificed animals (liver, lungs, entrails), by the lines in the palm of the hand, by the casting of lots, and by the “spirits” of the dead.
Man’s natural desire to know the future is satisfied when he worships and serves his Grand Creator, for through God’s channel of communication He lovingly reveals ahead of time what it is good for man to know. (Amos 3:7) However, when men turn away from Jehovah and become alienated from the only One who knows the end from the beginning, they easily fall victim to spiritistic demon influence. Saul is such a striking example, one who at first looked to Jehovah for knowledge of future events but who, after being cut off from all contact with God because of his unfaithfulness, turned to the demons as a substitute for divine guidance.—1 Samuel 28:6, 7; 1 Chronicles 10:13, 14.
A sharp distinction, therefore, exists between revealed truth from God and information obtained by divination. Those who turn to the latter are often seized in violent convulsions by invisible demonic powers, sometimes working themselves into a frenzy by weird music and certain drugs. No such physical or mental distortions are experienced by true servants of Jehovah when moved by holy spirit to speak. (Ac 6:15; 2 Peter 1:21) God’s prophets in a sense of duty spoke freely without payment; the pagan diviners plied their trade for selfish personal gain.
Nowhere in the Bible is any form of divination given a good connotation. Many times in the same condemnatory texts spiritistic practices of divination are spoken of together with adultery and fornication. (2 Kings 9:22; Nahum 3:4; Malachi 3:5; Galatians 5:19, 20; Revelation 9:21; 21:8; 22:15) In God’s eyes divination is comparable to the sin of rebellion. (1 Samuel 15:23) It is, therefore, unscriptural to speak of Jehovah’s communication with his servants as a manifestation of “good” divination.
I see it, as we either trust the Bible,or we don't.
If we don't trust it, we will trust something else.
My question is, if you question whether the Bible is God's word, should you not even more so, question what you are getting yourself into, when you disobey a direct command from the scriptures? What are you really tapping into? Who is really communicating with you?
I see it like this...
Someone is given a manual, for an item.
However, they doubt that the manual can help them, so they listen to what others say, which contradicts the manual.
Apparently though, some find the manual misleading.
Contrary to this, I find it works perfectly.
I would not mind if you pointed out some or all of those contradictions you find in the Bible. In fact, I am sure some have been discussed on these forums already.
