We know this through the clear teaching of Scripture that God uses evil for good without being its author.
The belief that God is not the author of sin is rooted in a careful interpretation of Scripture. For instance, in John 8:44, Jesus refers to Satan as the father of lies, indicating that the source of sin lies not with God but with the adversary. Moreover, the narrative of Joseph in Genesis 50:20 shows how God sovereignly operates through evil actions for His good ends, demonstrating that He is not the originator of sin but instead uses it within His divine providence. This distinction is crucial in preserving God's holiness and justice while affirming His sovereignty over all creation.
