In the kingdom of Cardia, there was two cities that were separated by a mountainous wilderness. Between the two cities there was in ancient times a road built. This road was difficult, but the safest and surest way to get to the other city. But a certain deceitful fellow come one day to the beginning of the road. There he set up a booth where he sold for very cheap maps and compasses. These were to be sold so people could find their own way though the wilderness to reach the other city. Those who passed by the booth were promised that by using the maps and compasses they would reach the city faster. They would have more adventure and ease on their way. They would have none of the difficulty that would be found on the other way. The problem was that all the compasses were defective in some way. The maps were filled with many errors so that they could be of no value in reaching the destination. This deceitful fellow's ploy worked very well. Soon the old path was almost forgotten and grown over with plants and shrubs. Those who took what this fellow sold, soon found that it did not deliver what was promised. Everyone who used the maps and compasses became hopelessly lost. Many were dashed to pieces from falling over cliffs. Some were eaten by wild beasts. Some had the unfortunate demise of being eaten by a large dragon. None of those who used these defective instruments ever reached the intended destination. The king of this kingdom on hearing of this deception, sent his son to drive out this deceiver. He then sent out his servants to seek those who were lost and tell them the way back to the path and to give them a reliable map. Some listened to these servants and by and by came back to the path and reached the far off city. As long as they followed the map and stayed on the path, their journey went well. Others refused to listen and continued on their doomed quest.
This story while failing to illustrate all of the truth, does explain the truth contained in this proverb. "Whoever trusts in his own mind(or heart)is a fool, but he who walks in wisdom will be delivered." Proverbs 28:26. How many songs on the radio can you think of that tell you to trust your heart? This is the wisdom of the world. Trusting your heart is foolish. Like a defective map or compass, it will always lead astray. Your heart is evil and crooked. It will lead you into danger and doom. "The heart is deceitful above all things, and desperately sick; who can understand it?" Jeremiah 17:9 Nothing is more deceitful than your heart, why would you let it guide you?
God's Word teaches us the right way, the way of wisdom. If we trust in the Lord with all our heart and lean not on our own understanding then He will make our paths straight. Keep to the old paths found in God's Word. It is the best way. It will bring us to the heavenly city. It is the safest way and the way filled with true joy. This path is opened up to us by the righteousness and death of Jesus Christ who is the way, the truth and the life.
