@Alone.....Have you ever tried throwing out everything you have ever heard, and just starting from the beginning with a clean slate?
Start in Genesis and establish why humans are here? What assignment did God give them?
Then establish what kind of life God purposed for them in the beginning?
Ask what happened for them to lose that life, and be sentenced to this one, with all its trials and tragedies?
What did God do about the situation now that humans faced old age, sickness and death and had the propensity to sin? None of which were in his original plan.
Who was Jesus and why did he have to come to earth as a human? What was his mission?
In what sense is he a savior or a redeemer? Who is he saving, and what is he saving them from?
What did Jesus command his disciples to do, and why?
What will the final outcome be? What happens to the 'righteous' and what happens to the 'wicked'?
What is the purpose of reward and punishment, so obvious in the laws of God?
Answer those questions and you will have a fairly good handle on what it means to be a Christian.
Yell if you need help....
All the answers are in the Bible.
