There are a few discrepancies in the Bible, but none that alter the overarching story in any significant way.
It's simply due to human nature's tendency to error which allowed such discrepancies to creep in, through no fault of the transcribers' own.
Am I not a Christian simply because I know that there are such discrepancies?
Being a Christian isn't dependant on such, and you should be careful of making such claims.
I'm not sure what you mean by "discrepancies" when you say "there are a few discrepancies in the Bible".
Are you saying that God, in one place, contradicts what He says in another place? Every contradiction necessarily involves a pair of propositions, one of which propositions is true, and the other of which is false. In order for God to, in one place, contradict what He says in another place, He must needs, in the one place, affirm
truth, and, in the other place, affirm
falsehood. I, for one, refuse to believe that God has ever affirmed, or ever will affirm, falsehood; thus, I cannot charge God with having contradicted one or more things that He has affirmed.
I'm not familiar with any sense of the term "discrepancy" that is not inseparably bound up with the idea of a contradiction, or a contrariety, between truth and falsehood.
As far as I'm concerned, no Christian (at least, insofar as he/she is a Christian), will ever charge God's Word, the Bible, with consisting of one or more discrepancies in the sense of God affirming falsehood against the truth which He affirms. Being a Christian in the doctrine of
Bibliology is, indeed, dependent upon the denial that there are discrepancies in the Bible.
Christians are far more forgiving than those who reject God's word, who might use that against you in defence of their own rejection of God, whereas Christians are generally willing to look the other way.
They are, without exception,
irrationalists who reject God and His word; they do not defend, because they cannot defend, their rejection of God and His word. It is impossible to defend falsehood and error. As a Christian, of course, it is not even my place to
forgive those who reject God's word
for their rejection of God's word; in their rejection of God and His word, they are not sinning against me, but, rather, they are sinning against God. Such forgiveness, then, would seem to be God's prerogative, rather than mine.
