I have only a few favorites when it comes to various thoughts in Scripture. One favorite would be the Lord’s question to the disciples and Peter’s response in John 6. In relation to proverbs, I think the one that continually comes to mind is Proverbs 4:23, Keep your heart with all vigilance, for from it flow the springs of life (ESV). It means much to me because, knowing something about the nature of man, the facade man presents is so easily detected. He presents this facade because, in many cases, he is tired of the pain of letting others in.
This is NOT what the proverb teaches, but since I saw it for the first time, I have always given thought to this idea. A challenge for me, then, is to be able to penetrate the facade of a man. I can think of no better way of doing this than: 1) live the life of Christ, 2) speak the words of Christ. The defense mechanism of a person can be mighty hard to overcome, but if there is an opportunity to overcome it, why not use the Lord’s power to do so (Rom. 1:16-17).
These are some of my thoughts.
