When & Does your name get written in the Book of Life?

Sometimes I merely sit back in awe of our Lord. To think that througout my life I had been lied to and that I had bought in to the teachings of men. I realize today that it is only by the grace of God that He placed a desire in my life to seek out the truth in the Word, instead of being led astray by my own opinion, and other men's teachings.
 As far as I can remember I was always told that if I accepted Jesus in my life and said a prayer that my name would then be put in the Book of life. I have witnessed people mentoring others tell them to repeat after them a prayer and that today was there 'new' birthday because their name was now written in God's Book of Life.
 In Psalm 139 we read and invision a beautiful picture of our creation in our mothers womb. How wonderfully we have been knitted into life and how God new everything about us. In verse 16 we see this passage "Your eyes saw my unformed body. All the days ordained for me were written in Your book before one of them came to be." According to scriputure our name was written in God's book even before we were created. Amazing....... No prayer placed us in His Book. Nothing we have done, or could do, could place our name in His book. He alone writes our names in His book before we were ever created.
 Now, in Revelation 3:5 we find another place where this Book of Life is mentioned "He who overcomes will, like them, be dressed in white. I will never blot out his name from the Book of Life, but will acknowledge his name before my Father and His angels." This passage lets us know that our names are in the Book, but also that if we do not overcome, He can blot out our names from the Book in which it was placed before we were ever born. Are we getting the picture? Is it just me, or do you alos feel duped by what you have been told throughout your life. God is so good though because He has graciously allowed us to read the scripture and press forward towards the mark instead of sitting down on our laurels.
 It is so important folks to read the Word. Slow down and taste it, and do not snack on it. Many feel that they need to race through it to say "I have read the Bible in a year, or I have read the Bible through in one year for the last 10 years!" God is not like an auctioneer who speaks to us 90 miles an hour to see who is fast enough to win the prize. No, we are to be still and listen. If you take anything with us today take this with you "God has given us yet another day to marvel at His Word and see truth one more time." Now, what will you do with His truth~
