Christians care very much about who you believe. Is your belief in an utterly truthful source, which you can put trust in for your everlasting security, or is your belief in whatever current trends and social media stories are doing the rounds? As this famous first century Christian author wrote:
"I know whom I have believed, and am persuaded that he is able to keep
that which I have committed unto him against that day." 2 Timothy 1:12
A.V.
He spoke of his belief in the resurrected Jesus Christ, who had appeared to him (after his resurrection). The reason Paul's life was transformed by that encounter was that he discovered Christ to be Truth, Light, and Life, in whom alone salvation is to be found. That is why Christians who are concerned about matters of belief take Jesus' every word seriously, as recorded in the Bible. That is why the Bible puts such stress on knowing exactly who this Jesus is - the Son of God, not merely a good man who set a fine example. Following the resurrected Jesus Christ is what Christianity is all about, but if you are following a religious system, or think that religious ritual is important, the chances are you are not following the Christ of the Bible.
Related to this is the problem of only having an academic interest in Christianity and the Bible. That's guaranteed to mire people down in pedantic points and to miss the point of why Jesus was crucified then resurrected, and why he had to be fully God and fully Man. This is what a friend of mine recently wrote:
"Had [Christ] been merely human, he could not have been sinless. Had
He not been human He could not have died. Had He not died, He could
not have conquered death by His sinless life. Atonement could only be
attained by a sinless Man who was also God!
...Arguments about the authority and cultural relativity of the
scriptures are simply smoke and mirrors. If their authorship is merely
human, the Bible is fallible. If 'men spoke from God as they were
carried along by the Holy Spirit' (2 Peter 1:21), then the Author is
God Himself and we are fools to be questioning a text that ought
rather to be questioning us. The touchstone of credibility and
reliability is the character of the Divine Author, not the flaws of
His mortal secretaries.
Finite study (we are not capable of better) without reliance on the
infinite Mind of God is a completely illogical exercise - which must
lead to illogical deductions." David Andrews, p. 5 of The Sword mag.

This answer shows the chasm between unbelievers like yourself, and Christians who believe passionately in the person of the resurrected Jesus Christ. The question is, who do you believe, and do you know who this One really is?
