Here are my different concepts that I came up with for your logo:
#20 is a simple but memorable wordmark, centered on the cross. I designed this to make a clean & bold mark on your books.
#21 uses the same cross "to", and incorporates an ancient fountain pen to reference the bible and how they transcribed their scriptures with pen & ink.
#22 & #23 is my favorite concept, thus far. #23 depicts a dove bringing the sermon (in the form of the olive branch) to the pages of the book. The wordmark used has "Sermon" in a handwritten font and "To Books" in a more published font.
Thanks for looking. I look forward to hearing what you think! I would be happy to work back and forth with you on any of them; if you wish to see changes just let me know.
