One of the reasons I love teaching Calculus is because it requires students to use every math concept they have learned previously. All of the concepts they asked previous teachers, “When will we ever use this?” Is now used in Calculus and applied to real life applications and you never know what previous concept will pop up on a test or quiz. You must be prepared at all times.

The Christian life is a lot like a Calculus course. Life moves quickly, full of difficult problems, pop quizzes, and tests. Life is full of opportunities to peer tutor others (mentor), lead study groups (bible studies or home groups), and you never know when you will be called upon to answer a question (give a word of encouragement). So just like it’s important for my students to read their textbooks, it is important we read ours as well. Our textbook is the Bible.

Paul had taught and mentored His student, Timothy well. Timothy travelled with Paul and had seen the miraculous life of Paul first hand. Paul, always the teacher, last instruction to his protégée was simply: “All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work.” Paul encouraged Timothy to read his textbook.

Guys, we have an adversary that does not fight fairly. He lies. He accuses. He exploits our weaknesses. He uses fear, shame and condemnation to try to paralyze us. One of our primary weapons of warfare is the word of God. We must know the Word of God to confront the enemy lies and accusations, to shield us from fear and condemnation.

Friends, read your textbook. Let it breathe fresh-life into you. Let it teach you, rebuke and correct the enemies lies, train you in righteousness, so that you are thoroughly equipped for every good work.
