Even if they want to, many Christians find it hard to talk to others about Jesus. Is it possible this difficulty is because we're trying to speak a language we haven't actually spent time practicing?
To become fluent in a new language, you must immerse yourself in it until you actually start to think about life through it. Becoming fluent in the gospel happens the same way - after believing it, we have to intentionally rehearse it (to ourselves and to others) and immerse ourselves in its truths. Only then will we start to see how everything in our lives, from the mundane to the magnificent, is transformed by the hope of the gospel.
"Even the title of this book, Gospel Fluency, gets at a right understanding of the gospel: the message from God that must be spoken... Jeff's clear call, through compelling stories and biblical foundations, is to connect the gospel to all areas of life, and then speak it fluently to believers and nonbelievers alike."? - J. Mack Stiles, Author, Marks of the Messenger
