Books are expensive! It is getting more difficult for Pastors to buy their tools (i.e. books) Here are three suggestions that have worked for me buying books:
Honoraria can be invested in your library. Since this is extra money that comes in from various sources, why not invest it? When you buy books, it is not money spent—it is money invested. I had an agreement with my wife that such honoraria from weddings and funerals go to books.
Never buy a book you don’t need simply because it is cheap!
Invest wisely. This means invest in books you need in the immediate future, not the distant future. If you are going to preach on Romans this year, but plan to preach on Revelation two years from now. Do not buy books on Revelation when you need books on Romans
