Is knowledge enough to get us through life? I would argue that it is not. Let’s use an example that is near & dear to me, since my eldest just got his license: driving a car. You can study the handbook provided by the DMV office; you can memorize every motor vehicle regulation in your state; you can even get practice on a simulation machine. But, any of you who already have your driver’s license know that none of those things compare to actually getting behind the wheel of a vehicle and driving yourself.
Why, then, would we expect our spiritual lives to be any different? Simply attending church now & then or saying, “Bless you” when someone sneezes is not the same as having a genuine relationship with Christ. On occasions when I’ve had the chance to share my faith, I can remember several times when someone would respond, “Yeah, I believe in God.” Well, I hate to be the bearer of bad news, but James 2:19 tells us that even the demons believe that much, and they tremble in fear at the name of the Lord. In fact, Luke 4:41 goes so far as to say that the demons even understand that Jesus is the Christ! They know everything they need to know about the Lord, so what’s the problem?
Just believing in God and even believing that Jesus is the Messiah is not enough. That knowledge has to make a journey from your brain to your heart. Romans 1:21 is a good example – it says that although the people knew God, they neither gave him honor nor thanks. In other words, the knowledge was all in their heads, and not in their hearts. The Common English Bible translation puts it this way: “their foolish hearts were darkened.”
God wants us to know him, and not just know about him. You know the difference … think about your spouse and/or your very best friend. That person really knows you; in fact, he or she probably knows what you are thinking before you even say a word. They don’t just know facts about you, but they know your heart. God has written us a very lengthy love letter, and he wants us to know his heart.
