A person who believes that Jesus Christ died on the cross for their sins, and has Him as the Lord of their life, is a Christian.
Personally, I wish to know as much about my King as I can. Most of that knowing comes from the Scripture. Much of my knowing Him comes from trying to follow His teachings, thereby becoming more associated with Him. The Holy Spirit participates in guiding each Christian as an individual, by prompting the spirit of a person to execute God's will for their life. Prayer and Meditation also deepen the fellowship we have with God. His will in our lives is gleaned from the pages of scripture, coupled with spending time in His prescence through prayer.
Knowing more about Christ does not make one a Christian. I do not always take a literal view of the scripture, because a straightforward reading will reveal the context and style intended. I can be wrong, and try my best to be open to correction. God is truth, therefore that is what I want.
That was very nicely said. Thank you.
