Alot of times we have qouted the scriptures on false witness but we have less considered how tempting it can be to lie when faced with difficult situations. Abraham prayed to God and further enquired on how to survive Egypt with Sarah his beautiful wife without being killed by her would be admirers. The lord told him to declare her as his Sister...

Yes this has really called for a debate which i dont want to start here but i want to address the account of a young and inexperienced Prophet named Jeremiah .

He was called by God at a tender age with no prophetic schoolling nor mentorship. He was curious on how he would suceed as a prophet but the lord told him not to be too borthered about what to say to the people for he will speak through him.

Jer 1:9
Then the lord reach out his hand and touch my mouth and said to me "i have put my words in your mouth" NIV

When it is most inpossible to declare the truth ask the Holy Spirit to speak through you... The spirit of God will prevail on your thought and tougue and he would direct you on what to say....
It will surely be the TRUTH!

Thanks Op,
This here, obviously is for those who know the Lord their God.

I don't believe it was God that in fact told Abram to make up the claim that Sarai was his sister and not his wife.

Genesis 12 vs 10 - 20 (ESV)
------------------------------------------------------------------------------------------------------------------------------------------------------------
10. Now there was a famine in the land. So Abram went down to Egypt to sojourn there, for the famine was severe in the land.
11. When he was about to enter Egypt, he said to Sarai his wife, “I know that you are a woman beautiful in appearance,
12. and when the Egyptians see you, they will say, ‘This is his wife.’ Then they will kill me, but they will let you live.
13. Say you are my sister, that it may go well with me because of you, and that my life may be spared for your sake.”
14. When Abram entered Egypt, the Egyptians saw that the woman was very beautiful.
15. And when the princes of Pharaoh saw her, they praised her to Pharaoh. And the woman was taken into Pharaoh's house.
16. And for her sake he dealt well with Abram; and he had sheep, oxen, male donkeys, male servants, female servants, female donkeys, and camels.

17. But the Lord afflicted Pharaoh and his house with great plagues because of Sarai, Abram's wife.
18. So Pharaoh called Abram and said, “What is this you have done to me? Why did you not tell me that she was your wife?
19. 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.”
20. And Pharaoh gave men orders concerning him, and they sent him away with his wife and all that he had.

What you said there is what even John the apostle submitted that every born again ought to do, and that is let the Spirit of God lead and teach them all things, rather than for them to rely on preachers and pastors anymore.

1 John 3 vs 20-27 (ERV)
------------------------------------------------------------------------------------------------------------------------------------------------------------
20. You have the gift[a] that the Holy One[b] gave you. So you all know the truth.
21. Do you think I am writing this letter because you don’t know the truth? No, I am writing because you do know the truth. And you know that no lie comes from the truth.
22. So who is the liar? It is the one who says Jesus is not the Messiah. Whoever says that is the enemy of Christ—the one who does not believe in the Father or in his Son.
23. Whoever does not believe in the Son does not have the Father, but whoever accepts the Son has the Father too.
24. Be sure that you continue to follow the teaching you heard from the beginning. If you do that, you will always be in the Son and in the Father.
25. And this is what the Son promised us—eternal life.
26. I am writing this letter about those who are trying to lead you into the wrong way.
27. Christ gave you a special gift. You still have this gift in you. So you don’t need anyone to teach you. The gift he gave you teaches you about everything. It is a true gift, not a false one. So continue to live in Christ, as his gift taught you.

In fact, John proclaims what Jesus Christ taught, which is that we really wholly on the Spirit of God for all the teaching, guidance, comforting, counseling and help we need.

You are correct but it was not counted as sin against Abraham....But what about the case of Samuel the Prophet he was weary of Saul's response if he finds out he had anointed David in his place .... The lord specifically told him he should tell he went to sacrifice unto instead.

All many times we need to rely on divine wisdom on what to confess ....

Abraham didn't lie, Sarah is really his sister
