The Bible contains many different types of writing, including history, poetry, law, proverbs and letters. And these were written by many different sorts of people over a period of perhaps 2000 years or so. It can be difficult to track down what it teaches about a given subject. However, there are quite a few books that aim to present what the Bible teaches in a thematic and ordered way. These are generally called systematic theologies.
Wayne Grudem helpfully defines systematic theology as
... any study that answers the question, "What does the whole Bible teach us today?" about any given topic. This definition indicates that systematic theology involves collecting and understanding all the relevant passages in the Bible on various topics and then summarizing their teachings clearly so that we know what to believe about each topic.
As long as we don't put these books at a higher level than the King of Books they can be extremely useful.
