Why did you say, "She is my sister," so that I took her for my wife? Now then, here is your wife, take her and go. (Genesis 12:19)
Lying always brings repercussions whether they take place within the family, in the workplace, at school, in church, or in the marketplace. Everyone at some point has been guilty of lying. The question needs to be asked is, "How do we deal with lying?"
Abram was guilty of lying when he went down to Egypt and told his wife Sarai to tell them she was his sister. Pharaoh took Sarai to be his wife and God sent plagues to keep him from committing adultery. When Pharaoh realized that she was Abram's wife, he rebuked Abram and escorted him out of the land.
When my kids were growing up and a misdemeanor was committed I would ask, "Why did you do that?" That was always the wrong question because they never had an answer. The question I should have asked was, "What are you going to do about it now?" This question calls for confession and change, and change benefits the accused.
It's far better to face one's sin honestly before God, than to try and perpetrate a lie because one necessarily leads to another and another. Make it a practice to take all acts of sin to our living and forgiving Father.
