Let me give you my testimony of my salvation.So you had no Christian faith before you started reading the Bible?
My parents took me to a small Methodist church sporadically as a child. What I took away from those times were Jesus loves me and do unto others as you would have done unto you. Good things for sure, but never heard anything about having to be saved from damnation.
When I was ten years old, one evening I was sitting on my living room floor looking at a Sears Christmas catalog I believe and my father was watching a Billy Graham crusade on the TV. As Billy preached on I was listening. As you know, Billy always stayed on point and preached the Cross of Jesus Christ and salvation. That evening before before falling asleep I prayed to Jesus Christ, confessed I was a sinner, and asked Him to save me.
At that time I never heard anything about Catholicism. Only heard a Preacher preaching the Word of God.
Later in my life at age 33, after going down a path of self destruction, God lead me to the Bible for the answers to life. I began reading the NT from the beginning. Read through Matthew, Mark, Luke and then I came to John and God slammed me when I came to "ye must be born-again". Woe! This is a "must". I never heard this before in my life, if Billy said it, as a child I did not catch that part, but I had to find out what this meant because it was a "must" for salvation. I went on a biblical journey at this point just to determine what this born again was and even if I myself had it.
Long story short, born again is born of God. Born of God is believes Jesus is the Son of God, the Christ. This is a "must be". The "Good Samaritan" is a lesson on Loving thy Neighbor. Ye must be born of God, believe Jesus is the Christ, for salvation from condemnation.
"If any man love not the Lord Jesus Christ, let him be Anathema Maranatha." (1Cor16:22)
"...for if ye believe not that I am he, ye shall die in your sins. (John 8:24)
"He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him." (John 3:36)
