Galatians 3:27 says "For as many of you as were baptized into Christ have put on Christ." The Timeline Room is filled with the names everybody in our youth group that has been baptized into Christ, along with the date of their baptism. The room serves as a reminder of just how important your name is to God.
In the book of Revelation chapter 3 verse 5 we read this very cool passage: "The one who conquers will be clothed thus in white garments, and I will never blot his name out of the book of life. I will confess his name before my Father and before his angels."
Wow. A book of life. Isn't it awesome to think about God writing your name down in a book that He keeps with Him forever in heaven?!?
