No. 2 Deadly Sin: Hateful Duplicity – a lying tongue (v.17). The original suggests learning the trade of teaching what is false. It is not a slip of the tongue; it is the trade of the tongue. People lie for many reasons, to cover up their sins, to make themselves better than they are. All falsehood opposes the nature of God. Lying is fraud, and is the opposite of God’s way. Lying intends to deceive or mislead people into accepting what is not true. We hear about white lies, wee lies, innocent lies, etc., but they are all the same; they are not the truth, therefore, lies. We know that the Devil is a liar and the source of lies (John 8:44). Falsehood is the sign of a corrupt heart, and it always leads to disappointment in the end. There is the father of lies, the Devil, on the one hand, and God, the Author of Truth, on the other.
