It is not how much you know the Bible that makes you a Christian; it is what you believe from reading the Bible that makes you one. In a nutshell, it is your faith in Jesus Christ as the sacrifice for sins that makes you a Christian.
"Jesus replied, “You, a respected Jewish teacher, and yet you don’t understand these things? I am telling you what I know and have seen—and yet you won’t believe me." John 3:10-11
You can read the Bible for a whole life time and never accept Jesus Christ as your personal Lord and Saviour. It may be that reading is your hobby or you just love stories. The Bible is not a story book but the Book of Life; it will be like a story book to you if it is stories that you are after. I know so many Professors of Theology who are not born again; it is just their profession.
Nicodemus was a Pharisee and not just an ordinary one; He was a leader of Pharisees and what you would liken to a Professor of Theology in this time of life. The major requirement of being a Pharisee was that you had to know all the first five books of Moses by heart and you had to be able to quote the same by heart. Nicodemus knew all these yet he did not know the simplest truth; the way to Salvation.
Not only did Nicodemus not know the way of Salvation, he also didn't believe the truth when the Saviour told him. Icons, it is not how much you read the truth in God's word that matters, it is what you believe and do with the truth that matters. You shall know the truth and the truth shall make you free.
Action Plan:- Go out to find Jesus in the word whenever you read the Bible and your life will change.
Prayer:- Open my eyes Lord to behold wonders out of your word.
