You do realize you are asking what requires a Bible study to demonstrate thoroughly, don’t you?
I can’t do a Bible study in a forum format such as this. But I can point out a few things and show Scriptures to support my claims. Of course, it will make no difference to you whatsoever.
- The term “christian” is a word to identify those who follow Jesus and believe he is the Christ (Acts 11:26)
- Jesus’ purpose is plainly stated in Scriptures, Matthew 1:21 She will give birth to a son, and y…he will save his people from their sins."
Jesus stated plainly his purpose, Jhn 3:17 For God sent not his Son into the world to condemn the world; but that
the world through him might be saved.
The Apostles who were followers of Jesus plainly stated his purpose, 1Ti 1:15 This [is] a faithful saying, and worthy of all acceptation, that
Christ Jesus came into the world to save sinners; of whom I am chief.
- Likewise the means by which we are saved is clearly written in the Scriptures, too.
So, to be a Christian, one must follow Jesus as that is what being a Christian means. (John 1:12)
And to follow Jesus, one must believe and adhere to these basic fundamental doctrines (Romans 10:9)
which Jesus himself taught and are indeed spelled out clearly in Scriptures.
"For God so loved the world that he gave his one and only Son,
that whoever believes in him shall not perish but have eternal life.
John 3:16
This is all crystal clear, yet I have no doubt you will focus on the idea that the words “basic doctrines” is not found in Scriptures followed by a list of thing to believe.
