Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus. Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things. Philippians 4.6-8
Start your day with prayer. My suggestion does not mean that you need to spend twenty or thirty minutes in prayer. Just be sure to start your day in prayer. Ask God to give you a clear mind and to help you understand your subject material. Remember God knows all your subjects perfectly, better than your teachers (wink, wink). Ask God to give you peace amid the chaos of your studies and busy schedule.
You must spend time studying. But you must also spend some time reading leisurely. This will give your brain a break from your studies, but not a break from exercise. I carry three books with me everywhere I go. Make sure that you always have something to read. If you are spending time with friends, or sharing a meal, you cannot read. In this case, talk about what you are reading, or what your friends are reading. Even if you read a children’s book, read, read, and read some more. Reading is exercise for the mind. Write everyday, in a journal, or compose a letter to a friend. Reading and writing will help to develop your thinking skills. Developing your thinking skills is important for you devotional life. At times the Bible can be a complicated read. Therefore, you cannot slothfully read the Bible.
Think on the Scriptures, you don’t have to read all day to think about them all day. I do some of my best thinking in the shower, after I have read a few verses, or listened to a chapter of the Bible. On occasion replace your music with an audio reading of the Bible. I am always encouraged when I listen to the Bible. If you live off campus and you have to travel in the car, listen to the Bible. But do more than just listen. Normally when I listen to an audio reading of the Bible I immediately repeat the words. I hear the Bible and I think or speak (out loud) the Bible. You can also make note cards that include a paragraph of the Bible. Take the note cards out during the day, in between classes, and work on paragraph memory. I recommend memorizing paragraphs rather than verses. You do not want to improperly understand the content of the text. As a college student, by now, you should be able to see the thoughts of the writer as they transition and change. If you are unfamiliar of this method, a good study Bible may be helpful to you. Sometime during the day designate a time to thoughtfully read Bible.
Before you go to sleep thank God for the magnificent brain that he has given you. As you sleep your brain will process what you have learned throughout the day. As you sleep, and get the rest that you need, your brain continues to work for you.
