Somethings need to be "unfolded" in order to use them in the best possible way. You need to unfold a napkin, or a bed sheet, or a blanket. If your T-shirts have been ironed and folded in your cupboard, you will have to unfold them in order to get dressed. To unfold something means to 'open it' or 'to gradually reveal.'
The same principle applies to the word of God - it needs to be 'unfolded' or 'unwrapped' in order to be revealed to us - this is when it is the most effective.
"The unfolding of your words gives light; it gives understanding to the simple." - Psalm 119:30
So, here is a thought - don't just let your Bible sit there and gather dust - Unfold it and then use it.
