I was reading in Proverbs 2:1-7 and noticed another place where we are given a reason for memorizing scripture. Of course the verse we use most often is Psalms 66:17 which says "I have hidden Your word in my heart that I might not sin against You." What a great reason! But in Proverbs 2, there is what I think is an evern more marvelous reason.
Proverbs two basically begins with a number of if's and then a statement of promise. I'll paraphrase: If you believe God's word, memorize it, beg God for insight to it, highly value it, then (and here is the wonderful part) you will understand how to approach God and you will come to know Him!
