@JLeslie that’s okay…it’s a fair question. As I stated, humans lie all the time. We are flawed that way. And people do it in the name of the Lord, all the time. But my take is that God doesn’t approve. Your question made me do some more research as well. I know that the Quran allows for deception if you are smoothing over differences or trying to get the upper hand on an enemy. I don’t know about Judaism though since it is based on Mosaic law (the 10 Commandments) I would suspect lying after swearing by God is likewise forbidden. Christianity decries it. The bible is full of references, in both the old and new testaments, that say lying is wrong: Here are a few. There are many, many, more, but you get the gist.
Proverbs 6:16–19 ESV
There are six things that the Lord hates, seven that are an abomination to him: haughty eyes, a lying tongue, and hands that shed innocent blood, a heart that devises wicked plans, feet that make haste to run to evil, a false witness who breathes out lies, and one who sows discord among brothers.
Proverbs 12:22 ESV
Lying lips are an abomination to the Lord, but those who act faithfully are his delight.
Proverbs 19:9 ESV
A false witness will not go unpunished, and he who breathes out lies will perish.
Psalm 101:7 ESV
No one who practices deceit shall dwell in my house; no one who utters lies shall continue before my eyes.
Colossians 3:9–10 ESV
Do not lie to one another, seeing that you have put off the old self with its practices and have put on the new self, which is being renewed in knowledge after the image of its creator.
Proverbs 12:19 ESV
Truthful lips endure forever, but a lying tongue is but for a moment.
Luke 8:17 ESV
For nothing is hidden that will not be made manifest, nor is anything secret that will not be known and come to light.
1 John 2:4 ESV
Whoever says “I know him” but does not keep his commandments is a liar, and the truth is not in him,
Ephesians 4:25 ESV
Therefore, having put away falsehood, let each one of you speak the truth with his neighbor, for we are members one of another.
But very few people practice what the bible preaches. I think lots try, but they are sinners nonetheless…we all are…and flawed so they fail. The best I think most of us (Christians) can hope for is to try every day. And no, this is not a recruiting pitch…I’m not trying to convert anyone.
