2 Timothy 3:16,17

All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:  That the man of God may be perfect, throughly furnished unto all good works.

The Bible is God's inspired Book, which provides for all our spiritual needs: "As His divine power has given to us all things that pertain to life and godliness, through the knowledge of Him who called us to glory and virtue" (2 Peter 1:3). The Bible is also the Book by which we will be judged at the Last Day. Jesus said: "He who rejects Me, and does not receive My words, has that which judges him - the word that I have spoken will judge him in the last day" (John 12:48). 

 If you are seeking for the  truth, true freedom and liberty, a meaningful life as well as the revelation of Jesus Christ our Lord, the the bible is the right book for you to use.
