Whoever trusts in his own mind is a fool,
but he who walks in wisdom will be delivered.
What is the character of a fool? The fool trusts his own heart, listens to his own counsel, and relies on his own strength and sufficiency. He trusts the good opinion he has of himself as if he had earned righteousness, yet he has deceived himself. As the prophet says in Jeremiah 17:9, "The heart is deceitful above all things, and desperately sick."
The flip side is the wise person who puts his trust in the Lord. He does not lean on his own understanding, but on God’s power and promise. The Lord is his shepherd and guide and comfort. The man or woman who walks wisely, who suspects his own heart, and seeks after submission and humility, shall be delivered; while the fool, who trusts in his own heart, shall be destroyed.
Our choices make the difference between life and death. So, choose wisely.
