Memorizing scripture is so important! What a blessing to have these verses and paragraphs and even chapters of the Bible hidden in your heart for the Holy Spirit to bring to mind at the moment you need it. We have found a great online tool for memorizing the Bible: Memverse. It is a very helpful program that allows you to put in the verses or chapters that you would like to memorize. Every day you can work on it, and it tracks your progress. Once memorized, it will occasionally remind you to study that verse so that you do not forget it.
We have been using this for over a year, and still think it is an excellent tool. Be sure to try it out. Make scripture memory a part of your life (whether you use this tool or another)--it is vitally important.
