“The law of the Lord is perfect, converting the soul; The testimony of the Lord is sure, making wise the simple;” (Psalm 19:7, NKJV)
Reflection: Do you want to look at something perfect? Gaze into the law and you will be laid low as you see God's perfection against your own imperfection. David said it "converts the soul" or in the Greek Septuagint, the word for "turn" or "return" can be used here which means there is a transformation which takes place.
Application: Given the power of God's word in the law, we should use it to help bring the knowledge of sin when sharing the Gospel. Hold a righteous, holy standard before sinners to give them a reason to run to the Savior, Jesus Christ. Go share God's word and help them to understand their condition.
