Concatenate Numerous Files

Hey!
I wanted to find a text version of the Bible for purposes of grepping. The only files I could find, (in the translation I wanted), were Old Testament.txt and New Testament.txt. I thought, "fine, I'll just concatenate those two, no problemo." But when I unpacked them, turns out they had each major book in it's own directory, often containing multiple text files. For example:
Code:
~/Desktop/New Testament/Colossians:
Colossians1.txt	Colossians2.txt	Colossians3.txt	Colossians4.txt

But, my faith in unix is strong, (possibly due to the depth of my ignorance). Can cat put all this together into one file - in order? I mean, the man page says that cat reads files sequentially, but what does that mean? If the directories were in order, (they're not now, I'll have to do that by hand), would cat work through them sequentially? I don't even see a recursive flag. Will it even move through directories? The truth is, I've only used cat to read files - not to actually concatenate them. Maybe I could feed it with ls, somehow?
I guess what I'm asking is, is there a one-liner that would get me through this, or am I expecting miracles?

cat(1)							      General Commands Manual							    cat(1)

Name
       cat - concatenate and print data

Syntax
       cat [ -b ] [ -e ] [ -n ] [ -s ] [ -t ] [ -u ] [ -v ] file...

Description
       The  command reads each file in sequence and displays it on the standard output.  Therefore, to display the file on the standard output you
       type:
       cat file
       To concatenate two files and place the result on the third you type:
       cat file1 file2 > file3
       To concatenate two files and append them to a third you type:
       cat file1 file2 >> file3
       If no input file is given, or if a minus sign (-) is encountered as an argument, reads from the standard input file.  Output is buffered in
       1024-byte blocks unless the standard output is a terminal, in which case it is line buffered.  The utility supports the processing of 8-bit
       characters.

Options
       -b   Ignores blank lines and precedes each output line with its line number.

       -e   Displays a dollar sign ($) at the end of each output line.

       -n   Precedes all output lines (including blank lines) with line numbers.

       -s   Squeezes adjacent blank lines from output and single spaces output.

       -t   Displays non-printing characters (including tabs) in output.  In addition to those representations used with the -v  option,  all  tab
	    characters are displayed as ^I.

       -u   Unbuffers output.

       -v   Displays  non-printing  characters (excluding tabs and newline) as the ^x.	If the character is in the range octal 0177 to octal 0241,
	    it is displayed as M-x. The delete character (octal 0177) displays as ^?.  For example, is displayed as ^X.
