Genesis 18:15

Then Sarah denied; saying, I laughed not; for she was afraid. And He said, Nay; but thou didst laugh. In her chagrin at being discovered, Sarah hastily denied the charge, but the Lord added a second reproof, convicting her of her falsehood. As the following events showed, Sarah accepted the reproof and turned to the Lord in true faith, for through faith she received strength to conceive seed, and was delivered of a child, Hebrews 11:11. Even now the Word of God reproves the sins and weaknesses of the believers, especially their lack of trusting faith. And we should at all times receive His reprimands with all humility.
