That You May Believe

³⁰ And ^(A)truly Jesus did many other signs in the presence of His disciples, which are not written in this book; ^31 (B)but these are written that ^(C)you may believe that Jesus ^(D)is the Christ, the Son of God, ^(E)and that believing you may have life in His name.

^16 (A)All Scripture is given by inspiration of God, ^(B)and is profitable for doctrine, for reproof, for correction, for ^[a]instruction in righteousness, ^17 (C)that the man of God may be complete, ^(D)thoroughly equipped for every good work.

A Warning

^18 [a]For I testify to everyone who hears the words of the prophecy of this book: ^(A)If anyone adds to these things, ^[b]God will add to him the plagues that are written in this book; ¹⁹ and if anyone takes away from the words of the book of this prophecy, ^(B)God^[c] shall take away his part from the ^[d]Book of Life, from the holy city, and from the things which are written in this book.
