From the essay in the op:
"The most important thing is that we believe in Jesus.....I don't believe in resurrection. I don't believe in eternal life. I don't believe in life after death. I don't believe in the hereafter. Those are all opinions. I simply trust Jesus that He will deliver to me as He rose from the dead, He will raise me."
Shazam. Who's opinions? And why trust or believe in Jesus if there were no resurrection, no eternal life, no hereafter? Didn't Jesus teach a resurrection, eternal life and a hereafter?
The point being, but this may be too subtle for some, is the object of faith a WHAT or a WHOM?
Many religions make claims as to resurrection, life after death, some reward in the hereafter -- all such claims are either promises or opinions because no one of us have ever stood up from physical death then told anything about it.
Jesus made claims and promises. The verity of his claims was demonstrated in his resurrection. However, no one can "prove" that he was resurrected. Thus, our hope is by trusting in Jesus Christ, which by all natural measures is not "reasonable".

Salvation takes more than just a mental acknowledgment of a "whom", the devils know that Jesus Christ is the Son of God, MT 8:29, they believe and tremble, James 2:19, but they are not saved. Salvation requires beleiving the words of Christ and
believing His words means doing them, faith in Christ means faith in His words:
Lk 6:46 "And why call ye me, Lord, Lord, and do
not the things which I say?"
Jn 6:63 " It is the spirit that quickeneth; the flesh profiteth nothing:
the words that I speak unto you, [they] are spirit, and [they] are life."
Jn 12:47,48 "And if any man
hear my words, and believe not, I judge him not: for I came not to judge the world, but to save the world. He that rejecteth me, and
receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day."
Jn 14:23 "Jesus answered and said unto him,
If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him. "
Jn 15:7 "If ye abide in me, and
my words abide in you, ye shall ask what ye will, and it shall be done unto you."
Mt 7:24,26 "Therefore whosoever
heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:.....And every one that
heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand:"
James 1:23 "For
if any be a hearer of the word, and not a doer, he is like unto a man beholding his natural face in a glass:"
James 1:21 "Wherefore lay apart all filthiness and superfluity of naughtiness, and
receive with meekness the engrafted word, which is able to save your souls. "
Jesus words requires one to believe, repent, confess and be baptized for salvation, Jn 3:16; lk 13:3,5; Mt 10:32,33; Mk 16:16 and those that "believe in Jesus" will DO His sayings/keep His words.
