I think it's also worth noting that Christians don't agree on whether salvation in Jesus is unconditional or not, although they all read the Bible. They believe diverse biblical interpretations and church doctrines about salvation, which is defined as
Calvinism vs. Arminianism (unconditional salvation vs. conditional salvation). Some Christians claim that salvation is conditional, and they will quote a few scriptures they believe support their belief. Other Christians claim that salvation is unconditional (OSAS), and they quote a few scriptures they believe support their belief. Yet other Christians claim that speaking in tongues or baptism is required for salvation, and they also quote a few scriptures they believe support their belief. It's ironic that they all claim the Holy Spirit gave them "spiritual discernment" to properly understand the Bible, but it's obvious that they all contradict each other. They all cite the Bible in an attempt to defend their answers, even though their answers are very different and contradictory. They also believe that they are correct about their preferred beliefs and everyone else (including other Christians) is wrong about theirs, but they have the audacity to claim that the Bible is the word of God and Christianity is the only true religion in the world. In my opinion, there's no reason to believe them. It seems unreasonable to me for any Christian to assert that their preferred biblical interpretation and theology are correct while simultaneously claiming that other Christians are wrong, that their God divinely inspired the Bible, and that Christianity is the only true religion and is superior to all other religions. I think it's also unreasonable for them to expect non-Christians to accept the Bible as the final authority on moral issues and as divinely inspired by their God, yet they cannot agree on what the Bible actually teaches.
