"As vinegar to the teeth and smoke to the eyes, so is a sluggard to those who send him." (Proverbs 10:26)
"Therefore, since through God's mercy we have this ministry, we do not lose heart. Rather, we have renounced secret and shameful ways; we do not use deception, nor do we distort the word of God. On the contrary, by setting forth the truth plainly we commend ourselves to every man's conscience in the sight of God." (2 Corinthians 4:1-2)
