Proverbs 23:23 Buy the truth, and sell it not; also wisdom, and instruction, and understanding.
This verse teaches that truth is life’s greatest treasure. It is worth every sacrifice required to obtain it and far too valuable to exchange for anything this world offers. A wise believer spends life buying truth through diligent study, humble obedience, and faithful devotion to God. Having acquired it, he guards it carefully, stands for it courageously, and refuses to sell it regardless of the cost.
The world may offer wealth, approval, comfort, or success in exchange for compromise, but Scripture’s counsel remains: “Buy the truth, and sell it not.”
Four more commands to children (continues): [3] Buy the truth, wisdom, instruction, and understanding. The command to “buy” these things means to obtain them at whatever cost is necessary. Truth and wisdom are worth time, effort, sacrifice, study, discipline, and commitment. Many spend enormous amounts pursuing wealth, education, possessions, and pleasure, yet neglect the far greater treasures of spiritual understanding. God’s wisdom is priceless because it affects both this life and eternity. [4] Do not sell the truth, wisdom, instruction, or understanding. Once truth has been obtained, it must never be exchanged for popularity, convenience, money, compromise, fear, or worldly acceptance. Many begin well but gradually abandon truth for personal gain or social approval. The believer is called to hold firmly to God’s truth regardless of the cost. Truth may cost something to obtain, but it is worth far more than anything it may require us to surrender.
