Doubt — The Sin That God Hates Most
Of all the sins we can commit, doubt is the one most hated by God. According to both Old and New Testaments, our doubting grieves the Lord, provokes him, causes him much pain. We see a prime example of this in ancient Israel, after God delivered his people from the hands of Pharaoh.
The Psalmist laments, "We have sinned with our fathers, we have committed iniquity, we have done wickedly. Our fathers understood not thy wonders in Egypt; they remembered not the multitude of thy mercies; but provoked him at the sea, even at the Red Sea" (Psalm 106:6-7).
