It always impresses me when someone can quote scripture that is appropriate to the situation at hand, especially when they can quote it word for word, and know the reference. Being impressed isn’t really because of their knowledge, but because if they can quote exactly what is in scripture, and tell me where to look it up and get more information means that I can know the truth from the Bible.
In Matthew 4, Jesus has spent 40 days and 40 nights fasting. I think that would make it very difficult to remember anything clearly. However, when tempted, Jesus is able to quote the necessary scripture to answer the temptations brought to him by the tempter. When tempted with food, Jesus quotes Deuteronomy 8:3, “Man shall not live on bread alone, but on every word that proceeds out of the mouth of God.” For each of the other temptations, Jesus again quotes Old Testament scripture that answers the temptation directly. Because of these answers, the devil leaves Jesus.
How awesome is the power of scripture. We can rebuff temptation with scripture in the same way Jesus did. However, it requires us to know scripture, to memorize it.
I often find myself being able to paraphrase things, and maybe being able to get somewhere close to where it is found. If given time, I can find it. While this is helpful, it often falls short of what I need. When I am having a difficult time, or trying to help someone, it is frustrating not being able to find the verses needed to help with the problem.
I encourage you to learn and memorize scripture. Jesus is our example, and he knew the scriptures. We should all follow that example.
