Titus is a letter to... Titus! He was an 'overseer' (or bishop) with oversight of many churches and this letter is (probably) from Paul giving him instructions about being a good leader. It's got loads for all of us to learn from.
We're taking the book of Esther in four sections to see what we can learn through the example of Mordecai and Esther. It's an interesting book to have in the Bible as God isn't mentioned once! But He's still there, working in all the goings-on. Take a look.
