You say, "But this was Paul writing, and Paul was just a man?" A man, yes, but he either lied or he told the truth regarding his presentation of the scriptures. What did he say regarding his writings?
Either they lied or told the truth. If there be a god, is this so hard to fathom? A human executive can dictate a letter to a secretary, and edit it with her or him to certify that the language is correct. Can not God do as much?
Then you say, "There are contradictions in the Bible."
Between various versions and texts, there do appear to be discrepancies.
The truth remains is, it is God's word and even if you're not up to scholorly endeavors (no shame in that, most of us aren't) there is adequate material that one needs not be ignorant of scripture, nor needs be convinced of non-existant flaws in the scriptures.
And remember, it is God that imparts wisdom. And how do we get Him to do that? First, become acquainted through Jesus Christ, for the man Jesus is the mediator between God and man.
And then ask him, for God is rich to those who ask Him.
Amen?
Amen!

That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of him.
Eph. 1:17
Reading that section of Ephesians one finds out that it continues to say,
I Cor. 12:1
For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ.
Galations 1:11&12
II Peter 1:21
The geneology of Christ appears different in Matthew than in Luke. Two crucified with Christ in Matthew both reviled him. In Luke, one repents and is promised Paradise. Through and through appears to be contradictions.
The key is, "appears" to be.
A more careful and comprehensive study of the scriptures themselves, sometimes referring to textual sources, reveal that the geneology of Matthew is regarding the line of Mary the mother of Jesus, who apparently was fathered by a man named "Joseph." Scribes often did not understand this, and being unfamiliar with other texts, such as those of Luke, sometimes (not always,) recorded the word "husband." Meanwhile, the geneology of Luke was of Joseph the HUSBAND of Mary. (And supposed father of Jesus.)
The repentant man crucified with Christ in Luke was a malefactor, one of two led and crucified with him. The two revilers in Matthew were thieves, two led after, and crucified later, on Calvary and who both rejected him. Early paintings of Calvary often depicted four additional crosses besides Jesuses' center cross.
Sometimes the apparent contradiction is because of poor translations from Greek, Aramaic, or Latin into our native tongue.
Sometimes we fail to understand idioms or figures of speech.
Sometimes contradictions appear due to our failure to understand clearly what is written. We may not know enough history, or might not understand the context or setting, or we may simply not have read the whole account.
Sometimes errors appear when we don't follow tenses or pronouns properly.
But repeated and thorough study helps give a serious searcher of scripture enough vision of the Bible's God-given pattern to see that there are no errors.
And to properly deal with errors in translation or inadequate grammatical knowledge, there are study helps: Bullinger's Companion Bible, his "Figures of Speech used in the Bible," his "Lexicon" are all a great help.
Strong and Young have excellent concordances.
There are interlinears (textual and contempary versions line by line to compare) and atlases and dictionaries and various versions of scripture for scripture analysis.
There are excellent studies of culture and common grammer usage, such as "Light through an Eastern Window" by Bishop Pallai. These are usually easy reads.
